I think you do know. It's fine if you don't want to tell me.

There's a ritual to it, isn't there? Wrench might not know what words Iggy spoke in front of the shrine, but he's certain they were calculated. The younger man wasn't simply chanting the first words that came into his mind. He must've thought they'd have some kind of impact, then. Needling any further just seems like bad form, though. Maybe the next time Iggy prays, if it all goes according to his plan, he won't even need to ask at all. Maybe the impact will be that obvious.

Oh, I thought I'd leave you out here as my own sacrifice. Wrench lets the implication hang for a moment until he can't help his own smirk. You found somewhere to stay already? He's not surprised; the locals have been more than generous with the summoned, so far as he's been told. It's not difficult at all to find shelter; he just hasn't taken anyone up on their offer himself.
