Damon blinks as Bonnie elbows him, and then he looks at her abruptly like What? He coughs lightly since oh yeah, he was staring. He folds his arms across his chest and then pokes Bonnie since he knows Elena is talking about Bonnie there.

It's not like Damon does hugs, and he's still speechless so he's not one for words at the moment.

Also, Elena is back, and it's like everything else settles into place now that he knows it and sees her.
