So I got the quest from the Hunter's Guild to test Tony. I went into the forest and made my way to the caves where the bats were. We won, I was seriously over-leveled, but when we automatically returned to the Hunter's Guild I had a brief moment before Isaiah vanished and then...nothing changed. I tried to talk to the Guild Master but he just had the same line about "if you find a likely candidate..." and Tony himself didn't respond at all.
Is there anything I can do to resolve this quest or do I need to leave it be? Did I do something wrong? I noticed Tony didn't actually join my party as a combatant I could choose after I spoke to him-I originally thought I'd gone to the wrong place and had to meet him somewhere first, so I was just wandering around the forest to explore. Then I killed the bats and suddenly Tony appeared saying "That was easy!" and whisked us away to the Guild.
