Swamped

"I don't know who you're referring to. I was guided here by your goddess."

He looks skeptical. You show him the key mold.

"She brought this to me so I could find you."

He snatches it out of your hand. That might have been unpleasant for him if you were actually trying to hold onto it.

"That's the thing the human woman was supposed to get for me. So pardon me if I'm not convinced. Although if it means getting out of this place, I suppose I don't really care; I just don't appreciate your weird human pranks."

"Does it not concern you that you were kept unconscious with an enchantment?"

"Look, I made a deal with her already, I don't know what you're playing at but I just want to leave. If she sent you along to pick me up, then let's get going already. If it's anything else, then quit wasting my time. Though I suppose it's good that the key-mold's finished. Can't be that much reason to delay in that case, can there?"

Well, if nothing else he's talkative. It's unlikely he knows much, but he shouldn't take much prodding to share what information he has.

"My apologies, I wasn't told the precise details."

"Ha! She didn't seem to think you were very reliable, I can see why. What more do you even need to know?"

As you thought. Hardly any prodding at all. Now you just need to think about what to ask.
