[... He barely recognizes this place at all; it's been long enough since he's been here, and also everything just looks completely different. He's wandering around, trying to get a sense of everywhere, mostly ignoring all the childish things around and focusing on figuring everything about this place out.
He might be walking around the park, kind of heading closer and closer towards the forests. All those signs of warning Chloe put up earlier? Eh, he's ignoring those.
Or he might be wandering around the underground tunnels, kind of interested in the one that's leading out deeper and deeper, without as many lanterns. Cause danger. Maybe stop him, since hey, how do you know if he's even armed or ready for that?]
