We all know Katherine is going to show up on the Salvatore's brothers doorstep. What snarky line do you you think Damon might say when he sees that it is Katherine on his doorstep?
Oh, now this is a good one. I suspect he will say something ironic but I'm not sure what.
Yes but Damon can do 1000x better I'm, sure it will be a memorable quote!
It would be hilarious if the first thing he does is to bite her then give her some snarky comment!
Then Katherine can return that by saying what he did to Elena as it's likely Elena will be jealous because biting/blood sharing/blood sucking is kind of intimate.
What do you think?
