"What did--- ah." That's right, the wisp. It had clearly caused this, as the memories (if that's really what they are) had been initiated by touching it. Now it's vanished. Why had it disappeared when he'd touched it, but not after Greg had?

Despite his confusion, he feels... better. Whole again. Whatever had sapped him of all hope before is gone, the emotion once again filling the gaps it had left. Had the wisp been responsible for this too? Hoes does he explain this to his friend?

In the end, he decides not to. The man in his memories, perhaps slowly seeping back into his general persona, keeps things to himself for good reason. "I... It's alright. Everything's fine, Greg. It's gone now."
