Thinking very hard about the role reversals in the lovesquare and how it’s going to affect season 5-
Marinette has always had trouble hiding her feelings. This is a plot point! She cant contain her fawning over Adrien most of the time, and usually can’t not speak up when Chloe or Lila bother her. She likes expressing herself, and she says what she thinks is right. It’s definitely a character trait of hers.
And, she avoided Luka when they broke up not because of anything he did, or how it ended, but because seeing Luka would bring on much too strong of emotions for her to handle for a while.
You see this in Ephemeral, too, before she started to accept Adrien as Chat she avoided any confrontation as even seeing an image of Adrien elicited too strong emotions for her to handle at that moment.
In a more negative example, look at all her failsafes to make sure she doesn’t know Chat’s identity. She’s trying to avoid Chat Blanc, avoid what she think caused it. Some of her favorite coping mechanisms are avoidance, distance, “think about it later after you’re done.” She needs time to process things, she’s had to compartmentalize so much of her life it takes time to unpack it, time she doesn’t usually have. It’s made her careful but it’s also made her solutions complex.
So how do you think she is going to handle not being able to trust Adrien? She’ll need to take her time, she’ll be heartbroken she can’t fully think of Adrien in her old light. She’ll avoid him.
The last conversation that Adrien knows Marinette and him had is the one about his situation, about his father. He was already hesitant to share his feelings under the influence of Risk, but...
I think there is a very good chance Adrien is going to assume Marinette is avoiding him because of what he said about his situation and his father. He’s very used to people not meaning what they say (Félix said he’ll help him, huh? His father sure doesn’t show he cares sometimes, huh?). He’ll assume Marinette said she understands to be nice, but ultimately, he made her uncomfortable with dumping his issues on her. And if Marinette, one of the nicest classmates in his school, can’t face him after what he said, then no one else can either.
So he’ll shut up, even though his father seems more erratic than ever, even with Nathalie’s declining health, even with Lila becoming more and more a part of his daily life. Maybe even if wielding so many miraculous causes Gabriel to be even more ignoring, or stricter, or angrier, or if his standards for Adrien become more unreachable, or he becomes so much more controlling...
What he thought was true. No one wants to listen to his problems. He just has to keep his head low, and focus on supporting Ladybug. If he doesn’t draw attention to himself, it’ll all be fine.
