oh come on. they are going to get back together, she is going to sleep with will, in the mean time you will find out the kid's girlfriend is related to the hooker, Cary is going to blackmail the other two after he finds out they slept together and Kalinda will finally come out of the closet!

Then the daughter is going to get mixed up in drugs, or become pregnant and it will bridge the gap between hubby and wife and then....

Just my prediction.

Oh and Dianne is going to get together with the redneck republican ballistics guy form a few episodes ago.
