I know I should like care about the fact Cas is just basically like "I am incapable of experiencing happiness my dear child so you don't have to worry" for Cas's sake but unfortunately all I can think about is how that must impact Jack.
Starting The Spear by Nicla Griffith and realizing with utter mortification that this is probably the first work based on Irish mythology I've ever read except (kind of) Fate/Zero.
Storytime: My brother Dave used to manage a Little Ceasars, and he hated it. So when my mom asked him what he wanted on his birthday cake, he jokingly said the Little Ceasars guy being stabbed with his own spear. My mom, who doesn't always get sarcasm, didn't even question it. She lovingly made him exactly what he asked for. It's my favorite cake ever.
helpful reassuring things to say to your CHILD who's dying wish was for his other parent to not be sad <3 literally all Jack WANTS is Cas to be happy and now (in his mind BECAUSE of him) if Cas is happy. he'll die!
still the funniest plot point in all of pmmm that Homura Akemi is a 14 year old magical girl who realized that her sparkly transformation sequence did not come with a cutesy custom weapon like everyone else's so she just went online and googled "how to build a bomb"
