My first reaction to theJJ/Reid storyline was that it was partially a diversion to cover the fact that they had new love interest for Reid planned, but they had us looking in a different direction, so that we would be surprised.
Actually, this is something that I have always wondered about.
It is not like the possibility. of it has not been there.
I do not think that they are teasing the two getting together.
You can have feelings for someone without a romance developing.
