(Requested: For Avy's Birthday!) Damon wants someone who won’t defend his bad behavior, and Bonnie calls him out on his actions. She won’t change him (personality wise) but she won’t tolerate him killing or even given up. She let’s him believe an alternatives choices besides jumping to the conclusion of the worst one. Gifset 9-12 showed the growth in Damon, usually he’d lash out, or get angry, but instead he walks away and accept the truth.
