Leisure Suit Larry returns just long enough to say howdy to Adama, and then blows himself up in a supposedly secure section of the Galactica. The Prez and Adama decide that they have to let the public know that there may be Cylons among them. While Starbuck adds to Baltar's paranoia, Adama appoints a Witchfinder General to figure out how Larry got aboard. She quickly discovers some inconsistencies in the reports from crew on the flight deck, and goes after Tyrol . Of course, the crewmen are actually trying to help cover up the ongoing romance between Tyrol and Boomer, because they're both so darn cute. One of the crewmen eventually falls on his own sword to save Tyrol's ass, claiming that he's the one who accidentally let Larry aboard. The Witchfinder has seen A Few Good Men too many times, so she puts Adama on the stand and demands to know why he kept the news about humanoid Cylons a secret for so long. Adama testily delivers a few lectures about civil liberties and paranoia, and eventually the Witchfinder and her whole Inquisition are buried under so many anvils that they collapse into a black hole. Oh yeah, and then Tyrol dumps Boomer. Back on Caprica, the Cylons arrange for Helo to "rescue" his own Boomer just in time for Valentine's Day. Aw.
Galactica. The PA of exposition informs us that the Scorpia Traveler has just docked with the Galactica, and that civilians are expected to go through security checkpoints. The camera roams through some corridors, and we see a line of civilians giving paperwork to armed soldiers. The camera moves around so that we only see the next visitor's back as he flashes a passport-ish book at the soldier. We follow this mysterious visitor as he moves down the corridor. The fact that half of the "previously"s involved Leisure Suit Larry makes me think this just might be he.
Elsewhere, Tyrol approaches Cally and asks, "All clear?" She says, "I've got your back, Chief." Tyrol enters the doorway Cally seems to be guarding.
Inside, Tyrol seals the hatch as Boomer greets him. They appear to be meeting in a water-tank room. Or something. I don't know, but it looks there's a small swimming pool in there, and it's probably not really a swimming pool, y'know? Maybe it's a hot tub. After a long hug, Tyrol asks Boomer if anyone saw her. She says no, adding, "I came through the hatch coaming on 'C' causeway." Plot point! While they kiss, I have a question about the way they refer to the "hatch coaming" throughout this episode. Everything I looked up indicated that the coaming is a kind of splash-guard (or flood-guard) around the hatch. So on a spaceship, I guess they're there to keep outer space from leaking in. That's just a joke, please don't yell at me. Sure, you want some kind of vacuum seals around the doors, but it seems as though claiming to "enter through the hatch coaming" or "close the hatch coaming" makes about as much sense as saying that you opened the door frame. I couldn't find any indication that this is special nautical-talk, either. If it is, I'm sure I'll get email about it.
The mysterious visitor continues to follow the line of less mysterious visitors through the corridors. Then he suddenly turns down an empty hallway. Right here is where they lost me. The big investigation looks pretty dumb when you see that Galactica's security system depends on people's being sheep-like and following the guy in front of them.
