Alec Lightwood 2x09
I get Raphael is trying to help Izzy and she definitely manipulated him, and that needs to be acknowledged, but she’s Alec’s baby sister, the one he would go to the ends of the world to protect her, like we saw in season 1, especially with that trial, he did everything in his power to make sure she was ok. Although, he has no excuse to hit Raphael he won’t be listening to reason or logic, he will not only be beating himself up for not seeing what was happening to Izzy but he’ll be lashing out.
I know Raphael is not to blame, NOT at all and Alec should know that, but he’s gonna make mistakes. He’s young and hot-headed and so so so scared for his little sister.
And Alec will realize his mistake, he just has to process it first, he did fuck up for sure, for lashing out at Magnus and Raphael but he needs to learn. That’s the beauty of it, seeing a character learn and grow and understand.
Family is everything to Alec and the idea that one of them is hurt terrifies him, he’s gonna blame himself and he’s gonna try and compensate by doing everything he can to fix things and because he feels guilty he’s gonna sabotage so much going on around him, like when it comes to fighting with Magnus, logically he knows it isn’t his fault but he’ll fight anyway, unconsciously pushing him away, unconsciously thinking that he doesn’t deserve him that the relationship might not be good because he let himself get lost in it and he didn’t notice Izzy spiraling.
Alec Lightwood isn’t perfect, but he is a good person, he’s just doing his best.
Also: (I have siblings and I know for a fact that they wouldn’t hesitate to punch someone if they hurt me, No matter the circumstances and vice versa)
