"I know," Derek tells him, looking down at Bitty's hand on his arm and then smiling at him. Bitty is just so sincere, so genuine and obvious about how much he cares, and sometimes Derek doesn't know what to do with it all.

"Stiles ended things between us," Derek finds himself saying, and it's strange. Bitty knows Stiles, or at least whatever version was portrayed on the show about them. It almost makes it easier to talk about him, in a way. "We sort of got back together here, on New Year's Eve. It was good for awhile, but then he was gone."

He swallows hard and then shrugs a shoulder, smiling wryly. "I'm okay now. It was just weird to be back up here."
