Wow I can't believe they listened to the viewers.
I agree they NEED to bring JJ back. It would be nice to have Prentiss but if I have to loose someoine well then it's Seaver. LOL
Seaver is nice but they should have launched her on the new Crimanal Minds spinn off show (I don't watch)
So to sum it up
JJ a must
Prentiss (if they can it's not necessary though
Seaver gotta go
