Yeah I will be upset if the coupling doesn't happen at the end of the season...but won't be surprised. We've had more hints and teasing this season than at any previous time before, and Kate's wall is finally starting to come down. They're relationship has evolved as well as they've become closer. I think the first step, will be that Kate will reveal to Rick at some point that she heard him say he loved her after she was shot. Remember he still thinks she doesn't remember anything, since he lied to cover her PTSD. I don't know how they're going to top last season's finale though. That is really what hooked me on the show and made me go back and watch everything beforehand during the summer time.
