Now we see there's a third element to Finn's snowy, woodlands duel with Adam Driver's Kylo Ren. Rey is part of the battle, too. We don't know how she fits in (although this looks a lot like the trailer shot of her weeping over a fallen friend), but as the Darth Vader-obsessed villain ignites the unstable blade of his saber, the untrained Finn is looking pretty unsure of himself. "Obviously that makes things a bit more tricky for Finn," Boyega says. "That's genuine fear."
