He wouldn't be spotted. He's fairly effective at hiding and being sneaky for obvious reasons. He's also not really that stupid to think he could just waltz in and out.

That being said, he'd sneak close enough to the camp so that Caroline would wander back in. He's gotten plenty of golden eggs from her anyway, and he's not selfish enough to keep letting these dickwads bother the village for a few shiny pieces of treasure.

Also sneaking. Goblin tolls will keep him in shape. /o/
