While Gary's stumped by the blast doors, Cameron's doing a pull-up to search above the ceiling for Rachel, which is just what a guy with a sliced-open abdomen should be doing. Sure enough, he starts bleeding again. "Why do we always have to fight other people with abilities?" Gary carps. "It's annoying." Meanwhile, Rachel comes to in her ventilation duct with zip ties on her wrists and duct tape on her face, but even so it's not hard to tell she's not happy.
Bill meets Rosen in his office and takes off his jacket, prepping for a shot. Rosen therapy-speaks about how he'd hoped Bill would be given the chance to make his own decision in his own time, and Bill says that kind of talk used to make him cranky. "I'm afraid it will again," Rosen says, jabbing Bill with the needle. Rosen says it should start working right away. Meanwhile, Rachel is wiggling along the airshaft. Rosen puts Bill to work trying to lift one of the blast doors, but the super-strength isn't kicking in, even though Rosen insists the drugs should be. He accuses Bill of not really wanting to get it up, not really, and of course he means the blast door, but he sounds more like an insecure girlfriend. After goading Bill some more to keep trying and watching him strain himself a bit longer, Rosen calls him off and says they need to go on the offensive.
So they all go to work trashing the place, squirting mustard and fire extinguishers everywhere on Rosen's theory that random, abstract colors will make it harder for Griffin to blend in. While they keep making a mess, throwing powdered creamer on the carpet (the best use it can be put to), Rosen stations Gary alone with a camera-equipped laptop next to a pillar in the middle of the lobby. Hard to see how that could go wrong. Soon the laptop camera captures running feet, and there are footprints in the creamer. There's confusion as everyone runs from one room to another, but everyone ends up locked in the MRI room -- except Gary, who's out there alone with her. I suddenly want to play chess with Dr. Rosen, for money. Bill tries to smash his way out, but Gary's got a plan to defend himself against the attacker: waving his DCIS badge around and ordering her to stop hiding. Well, that knife becomes visible again for a moment before the ads hit, but I don't think that's what Gary meant.
