The Doctor and the Owens men head back to the dressing rooms. Craig grumps the Doctor must have some magical alien "gas" that makes people love him. He even gestures at the Doctor's butt as he says this. Alfie (via the Doctor) tells his father he should believe in himself more. Not finding anything, they head back out onto the store floor. The Doctor thinks out loud. The silver gizmo-rat -- properly known as a cybermat, he says -- has been collecting power for the Cybermen. But why in a shop and not at a power plant? They bicker about the baby needing his diaper changed and Craig takes his son away in a huff. The saleswoman from earlier gives the lovebirds a worried look. The Doctor shouts after Craig, but stops when he sees Rory and Amy shopping. A little girl asks Amy for her autograph. The Doctor wants very much to say something to them, but makes himself hide behind a rack. Eventually he notices the big poster behind him, advertising a perfume called Petrichor. Amy is the spokesmodel. I think she's supposed to look mysterious, but she looks a little bit scared. "For the girl who's tired of waiting," reads the slogan.
As the store closes up for the night, the Doctor and Craig start skulking around in search of the cybermat. Alfie comes along via a papoose the Doctor gives Craig. They soon capture the cybermat, which seems kind of cute until it bares its rows of sharp metal teeth. Craig shrieks and has a bit of a freakout. At the same time, the security guard has just been attacked by a Cyberman and lets out an agonized scream. The Doctor bolts and finds him lying unconscious in the basement. The Cyberman knocks the Doctor clean out and the next thing he sees is Craig's worried face staring down at him. The Doctor gets up and stumbles around a bit, confused because the Cybermen shouldn't have been able to use the sonic-fused teleporter. Also, one of its arms was old and rusty. They've been abducting people and turning them into Cybermen with spare parts, but they didn't take the Doctor because he isn't "compatible."
