I understood Sarah saying she's not in love with Chuck because he hurt her, or even because he changed. I do not AT ALL buy the argument that she can't love him anymore because he killed someone when she's with Shaw. Frankly, it's really annoying. I can't love you, because your a killer, but I'm going to be with this other person who is 80 times more coldblooded than you and a killer. And I used to be with your absolute bastard of a best friend at Stanford who ruined your life on multiple occasions all under the guise of trying to protect you (which I do not find believable, because Bryce never stopped trying to snake Sarah). On top of the hypocrisy of that whole thing, Sarah is also a killer. And in light of that it's like she's saying Chuck's ONLY attribute was that he wasn't a killer, and once he transgresses that boundary he has literally no worth.
I mean, what? If you want to keep two people apart it's not hard. At this point, I think they're really overthinking it. A simple YOU LEFT ME ON THE TRAINTRACKS, I'M NEVER GETTING OVER THAT.
Now back to freaking out about my Mellon.
