Wanda couldn't, or didn't, want to save herself after losing Pietro. And yet, Vision did anyway. He contemplates why.

... vision being worthy hits differently after wandavision...

once again, warnings of pietro's death and wanda feeling suicidal after it...

Vision felt like he was carrying a frozen, limp, dead body as he flew away from the descending land of Sokovia about to implode onto itself.

Wanda Maximoff seemed… numb, for starters. But, Vision is aware that what she seems to be feeling was something, he probably did not know yet. An emotion powerful enough to render someone catatonic.

He did not know why, but now, he seemed to be feeling… He did not know what this feeling is. It is quite literally his first time feeling it, but, he thinks he’s feeling… sympathy, for Ms. Maximoff.

She appeared to be in a great and terrible amount of pain. And that emotion, as he understood it, was something that was not usually wished onto good people. And, despite Ms. Maximoff having worked with Ultron and Hydra, she seemed to be a good person that simply wished to protect her country and did not want to hurt innocents.

Yes, Vision felt… something, probably sympathy, for Ms. Maximoff… She did not deserve what had happened to her. Vision only wished he had the capability to give her what she needed in this moment.

However, he did not even know what that was. All he knew, for now, was that Wanda Maximoff could not, or maybe, did not want to save herself. But, that did not mean she was not worthy of being alive. And as such, he saved her. That was all he could do.

And yet, something inside him… sparked, making him want to do more…

But for now, he merely did his duty, and helped the young woman down as they had finally arrived onto solid ground.

They were a few yards away from where the rest of the Sokovians were evacuated and Vision wanted to make sure that Ms. Maximoff would be ready to acclimate to being surrounded by the tumult and noise of an evacuation area before he brought her there. And, it would be a good status check on someone that had just gone through an unthinkable loss and tragedy.

Wanda doesn’t- she can’t process it yet. She felt her body lose gravity, and then she felt it get lifted. Felt the wind and humidity from up above the sky.

She also felt the nauseating stench of the blood, ash, and smoke from the ruins of her homeland, or at least all that was left. Emanating to them even despite their high altitude.

She felt things, physical sensations after- … but, she did not even know what she was feeling anymore. She felt everything and nothing. She felt- …

She felt.

They were going down now and Wanda still didn’t think about what she was going to do. She didn’t want to figure it out.

But even then, Vision gently let her stand back on the ground, offering support in case she needed help standing up.

Wanda then, figures out the first thing she wants after what just happened. She wants to be alone.

She pushes Vision away and tells him as such, wiping the grime and tears from her face, “I want to be alone,” she inhales and wraps her arms around herself.

Vision takes a step back, out of respect. But, he’s still unsure how to handle this.

Nevertheless, he voices his concern. “Normally, I would respect your wish, Ms. Maximoff. However, we do not yet know if Ultron had other backup protocols in place in case his plan failed. And, I hope you do not think this as disrespectful, but, you do not seem to be in a fighting state right now, should anything happen.”

“I- …,” Wanda stops.

Not even a second after she was talking about something not about Pietro, she instantly remembers him.

But, she chides herself, how could she not?

How many times has she told Pietro she can protect herself? How many times- … She was with this person, her entire life. Every second she was not with him would be a glaring blaring agonizing absence in her life, a missing piece she knew she’d never get back. A hole, that would just forever be empty.

Reaching her hand out to only catch air.

She almost breaks. But, she doesn’t want to do this with someone else. She tells him off.

“I, can take care of myself,” she mutters, still not looking at him.

“Well, yes, I know that you are quite powerful, Ms. Maximoff. But…, as I understand you humans, grief and loss can irreparably change you. It would be quite understandable, and dare I say, humane to need help. It is not something to be ashamed of.”

“Ha. You do not know what I need. What I need-” … is my brother…

Fuck, she’s shivering again. She wills herself to calm down.

“I need to be alone, Vision.”

“But, if someone comes-” Vision steps closer to ask her to reconsider-

“Then let them come! Let them kill me and get it over and done with. At least-! … At least, I wouldn’t have to live in a world without the only family I had left.”

Vision, has nothing to say.

Wanda sighs, “Just go, Vision. Leave me be,” and waves him off.

Vision, realizes his place. And accepts it.

But, he didn’t know if it was safety protocols, or something else, but something inside of him prompted him to still ask, “At least, allow me to keep watch over you from the edge of the evacuation area, Ms. Maximoff...

I may not know you, your brother, or… the complexity and depth of what it is you are going through right now.

But, your brother gave his life so Mr. Barton and a child could survive. I’d assume he would want the same to happen for you, as well.”

- That’s, when Wanda breaks.

She can't-

She drops to the earth, and lets out the horrible wail that’s been building up inside of her all this time.

Vision, bends down to her, without knowing why he was doing so.

And Wanda, accepts his arms.

Wanda didn’t know what she was doing at this point except scream in anguish, shout her excruciating unbearable agony out onto Vision’s chest.

Despite having done this already and screaming her throat raw, the abyss inside her still goes on, feeling unimaginable and endless.

Vision, didn’t know what he was doing either.

He just could possibly not understand right now, what had possessed a tear to fall from his eye.

He feels himself embrace Wanda before he knew it. And Wanda feels herself grab onto Vis so tight, as if every ounce of pain begged to come out from her entire body. Vision feels Wanda's fingers grip his back so tight that although it didn't physically hurt, it still felt....

...

Humans. Odd. Possessing Grace… Is this- what, it must feel like?

Maybe Vision didn’t need to know, or maybe he didn’t want to know. All he knew right now, was that this person, Wanda Maximoff, was in pain. And right now, if sharing that pain with him, him feeling her pain, helped eased hers... He was willing to sacrifice it, without knowing why.

Humans, odd, possessing grace, anger, chaos, beauty, tumult, fear, pain, and love… he thinks it might just be the heaviest responsibility, and the greatest privilege. To feel what they feel.

Sympathy, empathy, affinity, love… is this- what it feels like?

Vision lets himself close his eyes and lie his head on top of Wanda’s almost protectively, to shield her from the world. And as he hears and feels her, still breaking down within his embrace, he lets the other tears in his eyes fall as well.

Vision, felt.

                             Notes:  

please tell me if anything felt romanticized or disingenuous or just... wrong, about Wanda's suicidal ideation and how she handled her grief... (but, uhm.. it's honestly based on what i've felt personally, my trysts with wanting to be unalive heh.. i'm asking because i've never felt a loss such as what wanda has felt, so... i want to be respectful so please, just tell me if- well as i said, just tell me. this subj matter shouldn't be written haphazardly so i take great care into making sure everything's treated carefully... that's all. i hope it's understood what my pov was on writing this is...)

wanda was stuck to where she had tried to kill ultron's main form was my main impetus on thinking she had given up on life... yes, she could just not have a handle on her powers at that point to be capable of flight. or she was just processing her grief and shell-shocked and not necessarily feeling suicidal...

this is just how i interpreted one could feel after such an unthinkable loss... once again, please don't hesitate to tell me if anything's wrong but... i still kind of hope i managed to evoke emotions with this work as it evoked something in me as i wrote it... thank you.

(also, this might have a next part. i'm open to it. i wanna imagine how the next part of their relationship, coming from this, develops...)

MQTT Client Certificate Authentication with Solace’s PubSub+ Broker

MQTT is the de-facto messaging protocol in the IoT world. When it comes to authenticating and identifying thousands of devices, you may see mention of client certificate authentication, but very little on how to actually achieve this. Although managing certificates, revocation lists, and everything that comes with being a certificate authority are complicated, getting started with client certificate authentication is not.

In this article, we will be performing all the steps necessary to begin creating a Node.js MQTT application authenticating via client certificates. There are three basic things we will be doing:

Creating a certificate authority (CA) and a client certificate

Uploading the CA certificate to the MQTT broker (Solace PubSub+ in this case)

Configuring a JS MQTT client to use the client certificate for authentication

There are a few things you need before we get started:

OpenSSL

Node.js

NPM

Solace PubSub+ Could Developer or Starter Service

Now let’s create the beginnings of an IoT solution!

First, we’ll create a certificate authority to sign client certificates using OpenSSL.

openssl req -nodes -new -x509 -newkey rsa:4096 -keyout root.key -out root.pem -subj "/C=/ST=/L=/O=/OU=/CN=root"

Next, we’ll create a client certificate that your MQTT client will authenticate with and a request to be signed by your CA.

How the client certificate is handled is dependent on your MQTT broker. This article will use Solace’s PubSub+ Broker which, in addition to authenticating the client, can use the common name (CN) or subject alternative name (SAN) to identify the client (see Solace’s documentation for more details). By default, the CN will map to a client username. In this article we’re using the CN “demo-client”.

openssl req -nodes -new -newkey rsa:4096 -keyout client.key -out client.csr -subj "/C=/ST=/L=/O=/OU=/CN=demo-client"

Finally, we’ll sign this certificate with our CA.

openssl x509 -req -in client.csr -CA root.pem -CAkey root.key -CAcreateserial -out client.pem -days 1825 -sha256

We should have all the files we need to continue. In particular, we’ll need the following files:

root.pem client.pem client.key

We now need to setup the MQTT broker. In PubSub+ Cloud, you require either a Developer or Starter service to take advantage of client certificate authentication.

The client certificate will be sent to the MQTT broker as part of the TLS-handshake. The validity of the client certificate will be determined based on the broker’s implementation. For the Solace PubSub+ Broker, this is done by uploading the CA’s certificate stored in root.pem.

In your service’s detail page, click on Manage, and then Authentication.

Under the Service Authentication tab, enable Client Certificate Authentication, then click Save.

You can also disable Basic Authentication like in the screenshot.

Back in the Manage tab, click on Certificate Authorities.

Then, click on the + Add New button. Choose a name, paste the contents of your root.pem, then click Submit.

Next, a client username must be created using the CN of the client. Under Manage in your service’s detail page, click on Access Control.

You will be brought directly to the Solace PubSub+ Broker’s management interface. Click on the Client Username tab and click on the + Client Username button.

Enter “demo-client” as the client username. Click on Enable then Apply.

Your Solace PubSub+ Broker is now configured to authenticate clients using certificates signed by your CA.

We can now finally setup our client and send and receive a message.

We’ll be using Node.js and MQTT.js to subscribe to a topic, send a message to that topic, and print out the message we receive via the subscription.

Create a file named demo.js in the same directory as the certificate files with the following contents:

**const** mqtt = require('mqtt'); **const** fs = require('fs');

**const** client = mqtt.connect('', { key: fs.readFileSync('client.key'), cert: fs.readFileSync('client.pem'), });

client.on('connect', () => { client.subscribe('demotopic'); client.publish('demotopic', 'Hello mqtt'); });

client.on('message', (topic, message) => { console.log(`Received message: ${message.toString()}`); client.end(); });

Replacing with the secured MQTT host of the broker (remember that the client certificate is sent as part of the TLS handshake, so insecure connections will not work for client certificate authentication). In Solace PubSub+ Cloud, in your service’s detail page, under the Connect tab, you can use the WebSocket Secured Host under the MQTT section.

Then run npm install mqtt in this directory. Finally, publish and receive a message with node demo.js. You should see the following output:

Received message: Hello mqtt

We now have the foundations of an IoT solution. There is more to work on from here, including how to provision, manage, and revoke the client certificates. Although this example used OpenSSL, you may want to look into more sophisticated solutions like Cloudflare’s CFSSL, Vault, or something managed from your favourite cloud provider.

As a bonus, Solace PubSub+ uses the same client certificate authentication for other protocols, so you can start using the same client certificate to authenticate with SMF, AMQP, and others. See the official documentation for more details.

I hope this helps you on your journey to connecting the world, one device at a time.
