Apparently being invisible really slows you down, because Gary's still untouched for the whole commercial break and well after it, although that knife keeps darting in and out of the shot. Suddenly Rachel runs up from behind and clubs the attacker unconscious with the laptop. Turns out the invisible woman is much more visible when motionless and flat on her face.
Cut to later, when she's duct-taped to a chair as Rosen shows her to the two dots and asks how she does the same thing with, you know, herself. Griffin offers to show them in exchange for cutting her loose, but she's not dumb enough to have actually thought that would work. Rosen brings up the "unsanctioned variable" phrase Kern used, although she prefers the term "ronin," which instantly lands her in a category of my own, labeled "tool." She says she's been on Kern's trail for two weeks, and offers to just take him off their hands. Rosen says that's pretty much the opposite of what Kern said. Griffin brings up the cracks Cameron's been noticing, and Rachel looks around and notices even more, on walls, and support columns, and even in the security glass she's standing right next to. Griffin duhs that their "sonic Alpha" has been trying to break out since he woke up. Rosen asks who she's working for, but she's not saying anything beyond that it's someone interested in Kern's research. She's already got that off their computers, but she gets a bonus if she brings in Kern as well. "Let's just call a truce. You let me take him out of here, I get my fee, you get to live. We all win." Well, except Kern.
While they're mulling that over, Rachel notices that Cameron's bleeding again. In the infirmary, Rosen can't stop the bleeding even with stitches, probably because of the vibrations going on. Cameron kind of mocks Nina's concern from the operating table as she stands over him and then notices that more cracks are spreading in the walls. Everyone who can do so rushes to the holding room, where Rachel is now able to hear the vibrations. Kern isn't looking too good either, all sweaty and evil, even as he says he wasn't hurting anyone. Rosen warns that Kern will kill himself too. "All I wanted was to bring more Alphas into the world. Why is that wrong?" Kern whines as the floor bucks under him. Rosen gives Bill an ether-soaked rag to go into the tank and knock Kern out with, but the vibrations have heated up the doorknob so Bill can't get in. So this high-tech containment facility has everything but oven mitts. All the metal, in fact, is getting so hot that Kern is able to snap the chain on his handcuffs (although the cuffs don't seem to be burning him or even singing the sleeves of his cardigan) and stand up. Then he turns and faces the glass wall, and, looking like the star of Mr. Magneto's Neighborhood, blows the holding tank clear open, flattening the team and blowing out every internal window in the office. He steps over them and heads out of the room. So much for the state-of-the-art Alpha tank.
