We cut to a hospital and see the woman on the other end of the line is a doctor. After patching the call into the interrogation room so, as she requests, Jones can hear the call too, Walternate asks what she wants. "Just for you to listen," says the doctor. She sets a little gizmo on top of the counter with what is some sort of electronic fuse or timer, and calmly walks away, leaving the phone off the hook. An intern accosts her, calling her Dr. Samuels and asking if he should give the little girl with the bike injury a tetanus shot. "Not necessary. I don't think she's gonna make it," says Dr. Samuels, leaving the intern befuddled. Behind her, the little gizmo starts releasing some kind of smoky gas, and as everyone in the ward watches, Samuels leaves, taking a crutch with her so she can jam it into the handles of the double doors. She watches as the soon panicked patients -- the first ones are parents with a little girl -- rush to the door in vain.

Back at Fringe Division, all we hear are the screams of the victims. In the hospital, the smoke has quickly filled the room while Samuels watches, and we can't see anything, save for a single hand that hits the glass in the door, and then slides off, leaving the skin of the palm behind and making a bloody smear, an image that gave me nightmares all weekend. You know, that gas is so instantly fatal that I'm not sure I'd stand behind two non-sealed doors to watch -- even the crutch would give a little bit, allowing some gas to escape -- but who knows how the homicidal mind works?

After the commercial break, we're back in our universe, where Fringe is tucked away nicely in the federal building. Olivia goes in to see Broyles, but he already knows about Peter and Lincoln Lee going on an unauthorized road trip to the other universe. He found out via word from his alter ego, who was just about as amused about it as Broyles is. Yeah, but you guys never smile, so no biggie. Olivia asks if Peter and Lee are OK. "They're fine. And we'll deal with the issue of your insubordination once we've resolved the situation," says Broyles. Ugh, there's nothing worse than knowing you're going to be punished but being forced to wait to find out what your punishment is. But Olivia's less worried about her impending execution for treason than she is about this "situation" that Broyles mentioned, so he starts filling her in, asking her if she knows David Robert Jones.
