It's not that he's falling for the good/bad(?) cop game, but more he joins in with suitable levels of patient annoyance. Get to the point already, dudes.

When they do, he's adamant that he has no idea how the ground decided to opt out of being Ground, seek higher opportunities for itself and such. He really was here looking around for the lost mine and some ~amazing forge of souuUUUUUULS~ inside, but it was the usual offscreen sidequest fare. Until the change of scenery. Now there's rope everywhere and a weird puzzle mine and he still hasn't found the forge. He's never taking jobs again. Can he convince you guys to give him a ride off whenever you're done with what you're doing? Like, he'll help you move crates and stuff. Please.

For Mista's insight: there is a lie here. Unfortunately, perhaps by the whims of an unforgiving dice god, he can't specifically say Where the lie is. Somewhere in the middle bit? Maybe they should press his testimony.
