Oh man, that is the BEST kind of plot, where a character you thought you hated or couldn't care less about is suddenly super-endearing. You know a writer/actor is good when that happens.
I KNOW!!! When you’re watching a movie or reading a book and have no expectations, and then when shit goes down you suddenly get really upset or you become aware of how attached you’ve become. That always happens to me at the end of a movie/book; suddenly it’s over and I’m left feeling alone and like I’ve been broke up with haha. It really is the hallmark of a job very well done.
