Well, these characters do often make mistakes and get themselves killed. Even the most intelligent ones.
First of all, he hasn't said "I'm not Bran" multiple times, he only said it one time. And second of all, I have explained to you 3 times already how I've interpreted his arc to have been him putting for an effort to improve his behavior with his family over the course of time. If you don't share that perspective that's fine, but you don't need to have a condescending attitude just coz you don't agree.
all you're doing here is having a "i'm right, you're wrong so deal with it" discussion with me. and that's not a discussion. you're not interested in hearing what i have to say and respecting it, only saying your perspective is the only one to go by
