When Sunny first takes the mirror out properly, Jae feels a sudden jolt of fear so unexpected that he actually jerks back a bit - his head hurts from it, staring at the twisted hallways that hold no truth, and the mirror makes it worse. He mumbles that it must be his own illusions freaking out at not being able to deconstruct anything, and spends the bulk of their journey out from then on clinging to Sunny's hand slightly behind his shoulder.

The sight of the dead creature puts him, contrarily, more at ease.

As soon as they can breathe again-

"I've never been this happy to be in a canton that'd kick my ass for showing up." At least he's out of the fucking tower. His voice is shaky with relief, like he'd been holding his breath without realizing it, but he's already less miserable being out of there.
