Exactly my thoughts/hopes on the plot with JJ. I was on my way to an important convention and was typing hastily my reply on my phone, so I was not as eloquent as you :-) but I agree completely.

Also, I found myself quite surprised with the almost squeal I made at the mention of Emily. I find myself hoping for a guest appearance on a case related plot (as there is probably no chance for her to visit with them just because...)
