One of the lesser Blue Danubes notes an energy fluctuation, and Periwinkle tears off for the holding cell. The assault team hustles into the secret passage, and the panel slides shut just as the Bluebirds run in, pistols ready. They look around the room and see everyone acting casual. "We detected an energy surge," Periwinkle says, "and it came from this chamber." T'Pol suggests that they have wonky equipment. Periwinkle turns to her and says, "Or perhaps you have equipment we don't know about." That's it! The sensor array is under T'Pol's shirt. The Blue Hawaii looks around one more time, and Quantum does his best to look pathetic. "Watch them!" Periwinkle orders his second-in-command, who stays in the room with the prisoners.

In the catacombs, the assault team finds the grotto behind the Big Rock Face and starts making preparations. They're using flashlights -- uh, don't you think the Blue Streaks might see beams of light flashing from the Big Rock Face's eyes and mouth? In fact, the Big Rock Face's orifices are so obviously hollow; why haven't the Blue Suede Shoes at least explored what might be behind the face, therefore leading them to the catacombs? I think the Blue Parrots are none too bright. They have good reason to be jealous of the Vulcan intelligence.

In the holding cell, the Bluegrass paces around T'Pol and says, "Most Vulcans smell of dust, but you're different." "Somethin' sure smells," Trip mutters. Yeah, and I think it's coming from the direction of this episode. "Did you say something, pink-skin?" the Blue Velvet shouts. Trip feigns innocence.

Catacombs. Reed and friends plant things on the wall behind the Big Rock Face and hear the NYPD Blues announce that they are picking up three new human bio-signs within twenty meters of them. The Blue Grottos panic around, trying to techno-locate the new bio-signs.
