Terra Nova Episode 1.09 Vs.

Lucas enters the Sixers' treehouse, and Mira asks, "What have you got for me today?" Meanwhile, Boylan admits to trading medicine with the Sixers for money, but he denies ever giving them information. He says that he doesn't know where Lucas is or how Mira communicates with 2149. Taylor doesn't buy this and keeps Boylan confined.

Josh and Maddy prepare for the Harvest Festival, which celebrates the day that Taylor first came through the portal. Zoe will be portraying Taylor in a stage play that depicts the colony's history.

After Taylor orders Reynolds to lead a medical supply run to a nearby outpost, Jim asks Taylor about Boylan, who's talking nonsense because Taylor drugged him to break down his defenses. When Taylor's called away, Boylan - hallucinating that Jim is Taylor - says that Taylor left the truth buried by Pilgrim's Tree, and if this were known, it'd be all over for Taylor.

Malcolm tells Jim that Pilgrim's Tree is where Taylor lived when he arrived at Terra Nova, and he provides its location. Jim goes there, digs up a skeleton, and brings it to Elisabeth, who says that this was a middle-aged man with half an arm missing who'd been shot in the ribs and buried for several years. Jim explains that Boylan tipped him to this and asks Elisabeth to determine the dead man's identity.

While the Sixers ambush Reynolds and company, a prehistoric dragonfly interrupts the Harvest Festival play's rehearsal. When a soldier swats it down, Maddy notices that the dragonfly has a microchip attached. Malcolm discovers that the Sixers are somehow directing the dragonfly and using it like a carrier pigeon to communicate with their spy inside Terra Nova. But the microchip is now damaged and so is the insect's wing, so they can't release it and track it to its intended destination.

Reynolds returns and tells Taylor that the Sixers knew everything about their mission. Washington observes Boylan was in custody when the mission was planned, so he couldn't have informed the Sixers. Taylor orders Boylan's release.

Meanwhile, Elisabeth discovers that the skeleton's DNA doesn't match up with anyone who's come through the portal; the molecular signature resulting from time displacement shows that this person somehow arrived between pilgrimages.

Jim tells Boylan that he found the body under Pilgrim's Tree. Boylan reluctantly explains that he helped Taylor bury the body. He doesn't know who it was, only that Lucas asked the dead man to come through the portal and Lucas has never been seen again.

Malcolm finds Elisabeth working on the skeleton and tells Taylor about this. Jim claims an anonymous note led him to find it. Taylor says that the body is probably a Sixer who falsified his DNA to cover a criminal record.

While Elisabeth worries about Taylor's finding the skeleton because she knows Jim won't stop his investigation, Malcolm tells Taylor that the dragonfly was traveling back and forth in response to a sub-sonic tone, and he's discovered what that is. He's also surgically repaired its wing and applied a tracking chip, so if the spy is still broadcasting that tone, the dragonfly will lead them to the traitor.

But now it's Harvest Festival time, and as the kids enact their play, Jim notices the child playing General Philbrick is pretending to be missing the lower half of his arm! Jim and Elisabeth have seen enough, especially when they remember news reports of Philbrick being killed in action but no body being found.

Meanwhile, the dragonfly leads Taylor and Malcolm to the Shannons' house, and Taylor arrests Jim on charges of spying. Taylor doesn't believe this, but he wants Jim to drop the investigation. Jim refuses and asks Taylor why he killed Philbrick. Taylor replies that it was him or me, and admits that Philbrick ordered him to give up his command - but the people who sent Philbrick also sent the Sixers. Taylor says that they want him dead because he discovered they don't see Terra Nova as a second chance, rather as an opportunity to strip this new world of its resources and send them to 2149.

Jim points out that people can only go from 2149 to Terra Nova. Taylor says when he discovered Lucas was working on changing that, he destroyed Lucas's work and Lucas left the colony. When Taylor tracked him down, Philbrick suddenly materialized and ordered Taylor to step down. Taylor refused, Philbrick attacked, and Taylor killed him. Lucas pulled a gun on Taylor, who disarmed him and banished him from the colony. Lucas vowed he'll see Taylor again, but Taylor hasn't seen him in five years.

Taylor adds that Lucas has continued his work, inscribing it on rocks that Taylor's found. (So have Skye and Josh.) Taylor claims that he's kept this from the colony less they become disheartened and give up. Then he asks Jim if he were in Taylor's shoes, would he let Terra Nova be ruined or fight back? Jim says he'd fight. Taylor sets him free.

As Jim reunites with Elisabeth, Taylor tells Malcolm that Jim's not a spy. Malcolm doesn't understand how the dragonfly misled them and accuses Taylor of planting a sub-sonic device in Jim's house. Taylor tells him to enjoy the festival.

Taylor then addresses the festival crowd, saying that we're all in this together and without all of you, I'd have nothing, so today I give thanks for all. When Taylor finishes his speech, fireworks light up the sky.

Somewhere in the jungle, Lucas listens to the fireworks...
