Well, they had to get Emily and JJ back, tie up loose ends and get the series back to normal. This episode did that and not a lot else.
I was bit bored, the episode was a bit predictable, I didn't care a lot about the boy and I'm left thinking "thank heavens that's over, now we can return to the good shows". While it is pretty good that the producers listened to the outcry of the fans re dumping JJ and Emily, they could have just done the normal thing and spent 10 mins chatting among themselves about the returning characters and then gone on to a proper case.
Roll on next week.
