This is no different from how it usually goes, except for once it's done in a place with relative safety and not some back alley or shitty apartment or a tree.]

[Kisses his cheek.]

It's okay. I've been told nightmares can't get you once you wake up. Just focus on me for a little, and it'll go away.
