I've missed a few of the new episodes, but look forward to catching up.  

I've heard, and correct me if I'm wrong, that Grace and Rigsby are back for the end finale.  They've already had their happy ending, but this show has always had a dark side.  Someone below mentioned Jane and Lisbon adopting a child, and I wonder if something bad might happen to GP and Rigs to allow this. 

Again, I've missed most this season, but I've heard there's another killer sort of theme going on or soon to be?  I'd love to see Michael Kirkland if he's alive, would be awesome.   

I don't hate the reveal as much as others, but can understand the frustration.  I think they've done and continue to do a pretty good job with this show.  I've watched and rewatched up to the end of season 6 and really don't have many complaints (not trying to make myself a target here, but I often disagree with a lot of the bad rep this show gets here).
