Peter just groaned and finished off his drink in one go - if they were going to do something crazy to find Carol the pokemon she wanted, he wanted to have enough alcohol in his system that he wasn't going to mind too much. He trusted her of course, Carol was just generally a little bit more of a risk taker than Peter, so things were likely to get crazy.
While he was making his peace with himself, Carol seemed ready to go, so Peter got to his feet ready to go with her.
"Of course, you think I'm gonna let you go out there on your own? I feel like I promised to protect you." He reminded her with a cheesy grin, because well he had - even if they both could take care of themselves it was nice having someone around to watch your back sometimes.
"Lead the way, we'll see if we can't find you one of the yellow ones." Sure it was cute, but it wasn't as cute as his bulbasaur.
