Back in the ring, Dinah uses her telekinesis to grab a short piece of steel pipe. And I don't mean she wrenched it out of the fence; there just happened to be this short length of steel pipe conveniently hooked on a section of the fence, like, how much less of an effort could this show possibly make? Dinah screeches something about getting "pissed," which makes Barbara say, "That's it!" She tells Reese and Dinah that after analyzing the drug's "antidote matrix," whatever that is, she's determined that the way to counteract the drug is to give Helena another dose, since that will flood the "amygdala" (the part of the brain that, according to my medical dictionary, concerns mood, feeling, instinct, and possibly memory for recent events) and shut it down, and let me give a big ol' whatever to that, since this drug was eventually supposed to tear Helena apart. Barbara tells Reese to find another dose of the drug. She should also tell him to take his hand away from his ear while he's listening to the radio, since it makes him stand out even more. Barbara tells Dinah to hang on, which is what I tell myself every time I watch a new episode.
So Reese goes traipsing off through the amazingly non-guarded corridors of Fight Club, trying various doors and finding them locked. When he's confronted by a guard who wants to know what he's doing there, Reese says he's looking for the restroom. "I guess this isn't it, huh?" For some reason, the guard doesn't buy Reese's story. Perhaps it was the way Reese delivered it all sarcastic and cocky and tough. So they fight, Reese slamming the guard up against the wall a few times and demanding to know where his boss keeps the drugs. The guard refuses to tell him, though, since he says his boss will kill him. Reese slams him against the wall again and says the guard should ask himself whether Reese or his boss will kill him first. So the guard completely caves in the face of such macho bravado and tells him the drugs are down the hall. Reese thanks him by slamming him into the wall again, knocking him unconscious, and dumping him on the floor right there for any other guard to find and raise the alarm.
