Gregor wouldn't know the first thing about the math looking solid, so he'll take Rosinante's word for it. Still, seems risky when there's a much surer option.

Speaking of which. He's taking a drink when he realizes that he's being looked at pointedly. Time to figure out how he wants to explain this.

"I don't know about souls, I honestly didn't believe in them before this. Part of me still doesn't." Maybe it's something else in the lantern. Life... force? That sounds even faker. "But as for the other thing..." Ah, to hell with it. What's the worst that could happen here?

"I would consider myself more of an exception than the rule. What happens to me probably won't happen to anyone else. I just have a tendency not to stay dead." He shrugs. "But I can tell you that I've never woken up with a lantern I didn't have before. So whatever that tells you."
