Eh, I had the same thought. I guess they were trying to show how traumatized the family was but it didn't really work for me. In fact the whole episode was meh. Except for the two guest stars - they did a great job. But the actual cast seemed to be sleepwalking. No standouts at all. I will say I liked the team up with Prentiss and Morgan and the cognitive interview scene was good. But otherwise, not exciting. Someone needs to get working and start churning out some kickass scripts - I hope this is not indicative of the writers/producers/directors attention being elsewhere (spinoff, I'm looking at you!).
Lastly, why was one of the kids naked? Were they trying to imply some "funny" (icky) businness going on there. I know they showed the close up of the mom's syringe marks, showing she had been forcibly drugged. But the naked kid made no sense to me. The other kid was clothed. And I also noticed the wonky, slow-mo walk to pick up the kid and then giving the kids to the mom and the beautiful "let's pan across our teams' faces" shot. All the while I kept wondering why they weren't getting them out of that place. Oh we're all together now, let stay huddled on this grimy mattress, not dress our kid and not try to leave.
And ditto to whoever said JM was not getting enough to do this season. Being Hotch's support is not good enough for *my* Rossi. START CRACKING SHOW, AND GET SOME SCRIPTS OUT WITH SOME MEAT ON 'EM. We've got some actors here that need to start chewing.
