waaaaaait. I'm confused. Are there two kisses? Because the one in the promo looks different from the one in the sneak peek.

This is my theory:

kasteel kisses Beckett first (the part in the promo), and in the sneak peak it shows Beckett kissing kasteel so I bet she pulls away of they stop kissing and then she kisses him again.

I don't know how this works considering the fact that I think it's just a cover anyway (because in the sneak peak Beckett is clearly looking somewhere else), but we'll have to wait and see.
