In 2149, Jim still isn't finished outracing the random explosions that are happening among the pipes in the dark corners of Hope Plaza, but he's brought up short by Weaver, bitching about how much he's cost them. Fortunately, the progressing explosions that were just on Jim's tail stop suddenly. And then Weaver gets eaten by the carnosaur, and Jim races on back down the long ramp to the portal, followed by the carnosaur once it's done chewing on Weaver. And the random explosions start again, along the ramp, as Jim heads for the portal, past guards who are flinging themselves over the railing and plummeting the hundreds of feet of open space below the gangway that makes it look more cool and futury.
Then there's a flash in the jungle in Terra Nova, and Jim's back, and the dinosaur doesn't seem to have followed him through.
Skye helps Taylor to his feet, at which point they realize Lucas isn't there anymore. Lucas is either some kind of ninja, or Skye is just really terrible at noticing things happening right in front of her.
And this big to-do over how the fracture dumps you somewhere else, which had Elisabeth worried, turns out not to be a big deal, because Elisabeth and the search party find Jim instantly, and he's all, "Told you I'd be back," and then they start making out.
But we're not done yet. It's nighttime, and Mira shows up at the terminus, where she finds out from Hooper that Hope Plaza's been blown up. "We're stuck here. Forever," he says, and Mira stares into the middle distance, telling us that Mama Bear is going to have something to say about this, next season! You know, if there were going to be a next season.
Over in the resistance camp, everyone's sitting around moping about the terminus being closed for good, and the Shannon family plus Skye get to hog the campfire.
Then Dunham brings a comm to Taylor, recuperating from his physical and psychic wounds, telling him Boylan's on the other end. Boylan tells him that Phoenix picked up and moved out about fifteen minutes ago. But they're not after the refugees. They headed north, although he doesn't know why.
So the resistance trudges home -- presumably after Taylor sent someone on ahead to make sure Boylan didn't throw in with Phoenix and was leading them into a trap -- for a happy reunion with the rest of the colonists.
