Both these couples have have more sexual tension than we can handle, and after years, they're finally ready to take their partnerships to the next level of frisky. Booth and Brennan got together at the end of Season 6, but fans were disappointed that we never saw them hookup.
Sounds hot — but hotter than Castle and Beckett? That remains to be seen. Caskett ended their fourth season in a fit of unbridled passion the likes of which we haven't seen since Scully eye-sexed Mulder back in the 90s. Sure, we didn't get to see their hanky panky on camera, but their makeout session was enough to keep us going for an entire summer.
Both these couples will be back at it in just a few weeks, and the time has come to decide which pair will have a hotter hookup. And yes, we give you permission to watch any and all makeout sessions in slow motion — this is a super serious decision you're about to make.
