Dear people who say Damon is only a monster; this scene is the only proof I need to prove 你 wrong. 

he picks up a tube that is literally pumping her blood out of it, and he doesn’t even react to the fact he’s holding an open 来源 to blood. He looks disgusted, worried and regretful. Because it’s hooked up to the girl he loves.
