It's his job.

[To hunt undead beings messing with the natural order; in retrospect it's surprising that Kravtiz didn't sense something off about the umbra staff during their little scuffle in Lucas' lab, but he was pretty distracted at the time.]

If we break it open now and another you comes out, I dunno what'll happen back home. It's been a decade, bubbale, another couple months won't hurt.

[It is weird, though, but he can't risk losing Lup for good, if this place messes with it all.]

Uh, Lucretia is doing her bubble thing, she thinks it's gonna work but... it's not, it's too late, and even if it does it'll destroy that world. Magnus and Merle are gonna see if Fisher will stop hiding the information about the Hunger, cause right now everyone's fighting shit they can't see. Davenport's gonna try to find the ship. You, me and Barry are going to Phandalin, one of the towns that got turned to black glass by the gauntlet, cause you've got a plan.

[He thinks it might have something to do with what Lucas said, about crystals, but he can't be sure.]
