Sora's going to come to a stop in the clearing and slip his backpack off his shoulders, setting it on the ground. He is going to go through this very slowly and very carefully, because he's pretty sure that if he doesn't explain this exactly right, the soldier will refuse to let him do this.

"Okay. So. You know how bad stuff happens if we leave our lanterns somewhere and go too far away from them?" He looks at his own star lantern's sun yellow, thinking intently. "I think... something extra might happen to me if I do that. So, I'm going to test that out and you're going to help me, because if the thing I think will happen does happen, I might need some help getting back to it."

Deep breath. He puts down his lantern between them, about as halfway as he can make it. "Whenever this happened to me in Locke City," he begins, trying to couch this info in the more recent past than the more uncertain past life, "I transform, and when I do, I don't really think in the same way? I kind of act like a dog. Holly - friend of mine, my little sister's best friend - called the other form 'Darky'. We'd play fetch until I turned back." Sora grins. "You don't have to do that. You just have to keep an eye on me."
