Wait. What about Simon? Wasn't he their mole in the government? Why isn't he warning Sophia about this? Where is he? We last saw him under a bridge, watching the uranium truck roll away. At the time, I thought he should be calling a helicopter or something. Or maybe setting up a roadblock. But instead, he just vanished off the face of the Earth. Maybe he's on vacation.
Martinez watches the exterior of Sophia's house (Oh, hey! I guess there was a reason they showed it to us before! Well played, The Event.) on a monitor in the Situation Room. He authorizes the Marines to go. But! Just then! Sterling says he's intercepted a heavily encrypted SMS that went to Sophia's phone and a lot of other ones too. And they see on the monitor that Michael Buchanan is with them, which doesn't surprise them all that much. They just sort of shrug. "Oh, that guy who was going to kill the president and blamed a mysterious conspiracy, then escaped from custody a couple of days ago? I guess he's an alien, but we didn't notice when we were treating him for that mysterious disease. Big deal." Martinez wonders why Sophia's going somewhere right after a text message, especially since she was holed up before that. She's only been holed up since they got there earlier in the episode, but I guess Martinez doesn't know that. He's just assuming that she's holed up because she hasn't gone anywhere in the ten minutes since they tracked her down. But he asks Sterling how many people got that message. Sterling says it's over two hundred. Martinez figures out that it could be a location, and maybe it went to all the aliens everywhere! He calls off the attack but has them follow Sophia. Because that worked so well last time, when he was using actual spies trained to follow people instead of soldiers.
Ambassador Hotel. There appears to be a ritzy shindig going on. Or it might be a swanky ringding. Sean and Vicky-in-a-wig enter. There's a metal detector and some security checkpoints. Sean looks twitchy and suspicious. He hands over the passports and invitations as Vicky and her cleavage hand over her purse and use the fingerprint machine. It's not all that suspenseful, because I don't believe for a second that they won't get in. Even when Sean's thumb isn't read properly at first, it's pretty flat. And they get in! So if you were filled with suspense about whether Sean and Vicky would get into the party, you can relax now. Seriously, take a breath and settle down.
