Broyles says this isn't the first time one of these has appeared; it happened in Quantico, where a colonel Jacobson led the investigation. Olivia happens to know the guy, which is awfully convenient, plotwise. Broyles says Jacobson is looking forward to a visit with her, so she goes to leave, checking in to see what Peter wants to do. "What kind of man would take off on you the minute a can of magic space soup appears out of nowhere?" He leans in close to tell her that this is the last one, and then he's gone. Olivia says OK, but doesn't look like she actually believes him. She leaves which means she misses Walter throw a temper tantrum when Broyles is reluctant to move the giant vibrator to Walter's lab at Harvard.
In Roseville, Va., Jacobson, played by That Guy! stalwart Nestor Serrano, greets Olivia with a hug on his front walkway. Inside, he talks about his wife dying last year, and says she took care of everything, and apologizes for the weak coffee. Olivia says it's fine. I mean, what else is she going to say? "I'm sorry your wife died, but that's no excuse for CRAPPY COFFEE"? Of course, this serves as a reminder to Olivia of John's death, which Jacobson knows about. Olivia gets all stone-faced at the mention of John's name, and asks him about what happened in Quantico.
Same basic idea -- a guard at the base noticed the motion sensors going nuts, and found an object. Jacobson shows her a picture of an object identical to the one that surfaced in Brooklyn. Jacobson's surprised when Olivia knows the object in Quantico was vibrating at two and four megahertz. "There's another?" he asks. She asks him if the other one is still at Quantico. Nope! Forty-eight hours after it appeared, there was an explosion unlike any he'd ever seen, and the object went down through the basement. "It exploded down, and was gone," he says, adding that Olivia can have his files, but if this shizznit is happening again, he advises her, as a friend, to get as far away as possible.
