Jughead wasn't about to sit still in an alien park. It was his instinct to look around and get a feel what this place really was. No pamphlet was going to explain it in a way that he would accept. It was just easier for him to take a look for himself.
"No, so I could see if it was horrible," He might have thought that all of this would be too much for Archie. So he really was glad that he got there first. That Archie hadn't arrived alone. "I haven't talked to anyone, except a dog. Which was a first." At least with the dog talking back.
Jug nodded, "Yeah, I'm fine. I found somewhere to stay in a place called Midnight," He figured it suited them. It didn't seem so bad either.
