Cat noir feels guilty leaving ladybug alone to fight hawkmoth and I think that’s why he doesn’t want have a back up holder, he doesn’t want to leave another person he cares about to deal with being a hero bc he can’t help.
And I think if/when Adrien finds out that Marinette was the one who got hurt because he wasn’t there, that she was tormented and haunted by a secret she kept while trying to protect him, I think it will destroy him
Adrien and marinette both try to protect each other to the point of self destruction, and I think that rather than feel betrayed by marinette keeping the secret he’ll feel like he failed her by again not being there to protect her from his father.
Adrien isn’t blind he sees how desperately marinette wants to tell him and cat noir knows that ladybug hates the feeling of having to keep secrets.
He also saw how devastated marinette was at the idea of hurting him, enough to turn into heartfixer
Season 6 has made a big point of saying that Adrien hates when marinette isn’t honest with him
They’ve purposely steered Adrien to be a character that hates being lied to so I’m scared that they probably will make Adrien get angry that they kept the secret
I feel like season 5 Adrien would of forgave maribug for lying but I understand that he is a traumatized 14 year old so I can understand that he has probably changed and that to forgive marinette on the spot would take a level of emotional intelligence unreasonable to expect of him at this time
I would love to see the show go a different direction than the civil war angst some people expect but know that the cards aren’t in my favor.
