Willem's arrival does not cause Gene any alarm, as he figures Willem is also a part of what was described. That theory is confirmed when Willem speaks of being sent there. Gene nods to him while saying, "Something very similar happened with me. I was told to join up with a group of people to retrieve a coin. Apparently to save the world, though I'm not sure how much weight that story holds. If it is true, I definitely want to help. If it isn't... I have another reason for doing this." He pauses, but decides against continuing with that line of thought. If they were to work together, there would be plenty of time to share life stories later, should they prove trustworthy enough.
When the half-elf speaks of knowing the mountain, Gene feels some relief. Having someone with experience of the terrain would be a huge help. He had never been up a mountain before, so a guide would be excellent, and he says as much. "I've never been to this place. If you're willing to help me... or us... find our way, that'd be a great help."
