My wishlist for season 7?  
Our recent discussion of "Hannibal" got me to thinking 'what if TM did that?'  You know, went back and started at the very VERY beginning. Let's see how RJ really got to know Patrick Jane and how Jane really got to where he was before he walked thru' the doors at the CBI.  
Yep, tough to do in 13 weeks and very little room for the rest of the cast but hey, give me a couple days.  Betcha I can make it work.
