Back to the Jack Patrol. Jack's wandering the hallway, looking for the bathroom, and Barbara orders Dinah in after him, since she can't let him out of her sight. So in Dinah goes.

Reese finds a yearbook and looks up Helena's picture in the mug shots, but hers isn't there. He's none too pleased at this, and I have to say I'm wondering why he didn't look through the rest of the yearbook. Or, you know, ASK SOMEONE TO POINT OUT HELENA KYLE. Sheesh.

Back at the men's room, Jack leaves and Dinah's right behind him, and I'd really like to know where she was hiding that she was right on his heels, yet he didn't see her, and I'd also like to ask what the point of this men's room excursion was. And she follows Jack down the hall, bumping into two guys who then give each other sly looks, and maybe the writers need to be reminded that Dinah's only sixteen.

Meanwhile, Helena's patrolling the hallway looking for Cam, which she complains is hard to do since she could have passed him a hundred times and not known it. Oh, and Barbara's constructing a device that will "stabilize his molecular structure," i.e. prevent him from disappearing. As if. This time, Barbara doesn't have to translate the technobabble for Helena, since she "bought a dictionary." Okay. And Gibson makes a comment about her vocabulary now being as exquisite as her beauty, and Barbara just stares at him.

Elsewhere, Helena runs into Drunk Guy in the hallway, and I'm surprised the guy can even stand up at this point. He refuses to look at her, for fear of causing her death. "Must avert eyes," he says. "Must return to party," she tells him, although you'd think an experienced bartender would know better than that. As Drunk Guy staggers back to kill more brain cells, Cam materializes right beside Helena (in full view of the many other people there in the hallway, I might add), plants a kiss on her cheek, and runs off down the hall. Helena gives chase, telling Oracle, "He found me." Cam leads her to a science lab, where she spies a couple of beakers full of coloured liquid attached to a digital timer with just over three minutes left on it. Helena asks Barbara how her bomb-defusing skills are and outlines the set-up, and you'd think the writers would shy away from using bombs on this show, since so many episodes could be described exactly that way. Barbara tells her to start with the timer, but before Helena can get to work, her legs are ripped out from under her. Oh yeah! The chameleon guy! Maybe she should have been looking out for him. Cam's disembodied voice tells her that the bomb will let off a deadly corrosive toxin and they'll die together in romantic bliss. Nuh-uh, says Helena. Yeah-huh, says Cam. Nuh-uh no returns, says Helena, who's concerned about anybody who might just be wandering by when the bomb goes off. Cam calls that "collateral damage" and says that one way or another, they'll be together. Aw. How sweet! Two minutes on the timer! We just have to sit through five minutes of commercials.
