Craig wonders why they haven't invaded by now, if they're so evil. The Doctor hasn't figured that out yet. He tries to get him to take Alfie home, but Craig is determined to stick with him. Being with the Doctor is the safest bet, he says. "You always win!" he says. "You always survive!" The Doctor gives him a sad smile, but can't refuse him. They split up to go investigate the shop, but not before the Doctor gives Craig an affectionate hug. A saleswoman at the jewelry counter sees this and gives them a big smile. "I hope you don't mind my saying, Doctor, but you look ever so sweet with your partner and the baby." The Doctor thinks about this. "'Partner,' I like it," he says. "But is it better than 'companion?'" She thinks that sounds too old-fashioned. He eventually gets around to asking her if she's seen anything unusual around the shop lately and she mentions the "silver rat thing." Meanwhile, Craig heads off to the lingerie department to ask Shona's former coworker some questions. He unintentionally comes off like a perv, things go downhill quickly and a security guard is called over. Craig tries to beat a hasty retreat, but knocks over a stand of delicates. The Doctor comes bounding over to help. The employees, clearly enamored of the Doctor after just his short time working there, back off when he identifies Craig as his friend. A bit of talking and they find out this is where Shona disappeared.
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.
