Jesus Christ when could the kid do that?! Well Strange wasn't expecting Yuya to just swing over the barrier like a circus acrobat. Strange rushes forward, parting the ice with his magic, only to see that Yuya's already made it halfway down the hallway...and Strange can hear the tell-tale rustling of angelic feathers from the other end of the hallway.

Yeah, screw this, he's out. He's no use to Nightshade if he's dead or captured. Strange walks back towards the reflective patch of ice on the wall and magically vanishes into it.

It's possible they'll run into each other later, considering how Strange's strategy seems to be 'travel through rooms until he finds the right path'. And they're definitely going to run into each other again at the ritual. But for now, Yuya's made a solid escape.
