Back with Jack and Caroline. He's explaining how Prophet Five is a far-reaching organization with connections to twelve major government agencies that they know of, and Caroline rightly assumes that following the micropulse bomb might be the key to finding out more about it. She's a bit perturbed that Jack's asking her to investigate her own agency from the inside, but Jack says that he wouldn't have come to her if this didn't involve Sydney as well. Caroline's all, Sydney? Is she okay? Jack's all, oh, she's fine. In fact, that pregnant chick who handed you the napkin outside? That's her! Caroline laughs and says that unless Sydney's wearing a very convincing disguise-- "I'm gonna be a grandfather," quips Jack. "A very YOUNG grandfather." Hee. I told you he gets all the best lines. Caroline congratulates him and tells him that Sydney's lovely, and Jack says she is and then goes on to tell Caroline about Vaughn's death. Caroline's sympathetic, but she still thinks investigating her own agency is risky. "That's treason," she says. "What's a little treason between old friends?" asks Jack.

Conference Room of Endless Expositions. It must be a few days later, because Jack's informing the troops that Caroline got back to him and confirmed their suspicions about a double agent at MI:6. She hasn't identified the double agent, but she did manage to identify the man who designed the weapon. Jack brings up his picture on the Wall of TVs, and it's Terrible Haircut from Siberia. His name is Basarov and he's a tenured faculty member at the University of St. Petersburg. Jack says that Basarov is on his way to a conference in São Paulo, Brazil, where he's scheduled to give a lecture on theoretical microdynamics. "Wow," says Marshall, "sounds awesome!" Jack just stares at him. "Well, you know, um, Brazil," stutters Marshall. "Isn't that the place where they have the, uh, string…oh, not bikinis but --" "Thongs," says Jack. "Yes!" says Marshall. HA HA HA HA HA HA HA HA HA. Oh, man. Every time I watch this, it makes me laugh just a little bit harder. Garber's expression is priceless. You just know the entire table of actors broke the hell up during this scene. Hell, they're barely keeping it together right now. I have to admit, I couldn't help but replay this scene in my head during the rest of the episode. 'Twas a mite distracting, but hilarious.
