"Ooh, nice," Kate says when he takes a green shirt off the rack and she reaches for it, holding it up against Derek's chest as well. Then she pulls it back and puts the blue back, which is nice, too. Brighter than the blue shirts he already has, which she knows for a fact because she has seen the inside of his closet multiple times.

"Yeah, what do you have against my store?" she asks, although she's teasing, which has to be evident enough in the grin she gives him. It's nothing against her store, she's sure of that, but's always fun to give Derek a hard time and right now she doesn't want to treat him any different just because shit got scary and hard while he was gone. It's probably better not to. "Ooh, I like how that sounds, though. My store. Hopefully it'll actually be my store one day and then he'll have to come in all the time, because I'll be the boss and somehow this logic works in my head, just run with it."
