This episode was kind of like "Lost', there was an interesting mystery, good character moments and in the end it doesn't make complete sense and the pieces don't really fit together. The Tally! The Tally Shall be Met! You'd need mass defibrillation!
They did a pretty good job with the trappings though. I imagine they might freak some kids out from going to the hospital, those guys were freaky, even if we don't know what the hell they were doing.
I love Amy's expressions in the hospital lift. Karen and Matt have a certain spark together. I am curious what they're building up to as far as a departure goes, this episode subverted my expectations.
I'm also curious to see if they will manage to make a good cube toy. Maybe a kitchen timer if they can get a half-way decent display effect.
