Dan gave him a slight smile. "I should get going..." he said, gesturing back to the door with his thumb. "And you should get some more rest" he added. "I'll be back at some point. Just make sure and take care of yourself, all right? No dwelling on the past" he said, trying to sound caring and playful enough. He reached out a hand and gently stroked the back of Mark's hand, before he turned to the door and left, closing the door gently behind him.
