Inside the house, Maddy has come to the conclusion that Horton is not the real Ken Horton but someone who stole Horton's identity to come to Terra Nova, and used a "facer" to provide a new face, because, oh why not a "facer." Then she gets a genius idea: she's got Horton's DNA on the envelope he sent her, so she just needs to get a new sample.
It doesn't take long; the next day -- after he fake-casually remembers that the colleague she was asking about was Dr. Grazier -- Horton leaves behind his coffee cup. Maddy grabs it and then uses the lab's DNA software to check it out. Malcolm comes in, concerned with what she's doing, but is super-eager to help out when he finds out it's because she thinks Horton's a fraud.
Over at Boylan's, Josh sneaks a vial of Azimeth from the package he's got for Boylan. Then he tells Boylan that his dad's asking a lot of questions. "The truth would be very bad for business," says Boylan, who then notices the skeet who tried to pawn the watch. Boylan tells Josh to go home and play the dutiful son, and no one will suspect him. Josh leaves. "Hey, Willy? How'd you like to work off that money you owe me?" Boylan calls, pulls out sonic pistol from under the bar.
Bad news for Maddy: the DNA is a match. "I was so sure. I'm sorry I wasted your time," she says, and Malcolm resigns himself to the "casual insolence" and being treated like research assistant. That last bit twigs with Maddy, who'd better act fast because Horton's skulking around in the shadows and has heard the whole thing, like this is some sort of medieval fairy tale of sorcerers and knights. At the infirmary, Willie's high as a kite on Azimeth and Elisabeth is examining him. She called in Jim to tell him about Willie's broken ribs and tissue damage consistent with a blast from a sonic pistol. Jim says he's going to have a look around Willie's place.
In the jungle, the Komodo makes its move, but Taylor scares it off by waving around a machete and a torch and calling it a coward. "Jesus, this guy's insane," hisses the Komodo before scuttling away. And when Curran wakes up the next day, Taylor gives him a map and orders him to infiltrate the Sixers. "You do it, Curran. Or the next time I track you down the last thing you're going to see alive will be my face."
