After reading what it all will be about, I think I thought it will be better, expected maybe something different - it was little slow in some points and the case.. I do not know - maybe it was a dead end as Rossi's unfinished business - you thought it will be mind blowing but when you see it, it was ok..
Anyway, this episode definitely goes down as one of the best char development episodes they have done. They have reveled before some facts about Reid, but this time his family is in focus and there are much to learn. And JJ and baby.. great addition to that episode..
