I'm doing a high-chaos run with Emily, and when Meagan revealed who she was, I stabbed her and brought the body to Anton.
And he broke down. Whoever voice-acted him did a fantastic job in making me almost cry. My rage against Meagan was well-founded, but she didn't need to die, and I just broke a sad old man's heart, killed his only real friend. And he was working on a painting for me. A gift, that I threw back into his face with the body of his dearest companion. So I reloaded the save, choked her unconscious, left her on the deck and headed for the tower.
I know it's a god-damned game, and I need to calm the hell down and let it go, but that really isn't sitting well with me. I wish I'd never done it.
