Olly knew this was serious business but he still sort of felt like a child pretending to be a ninja. It almost didn't seem like this was happening. Boys were missing. They were in the alternate Hogwarts now. The other side of the portal. This was the monster's home, its realm where it was most powerful. The reality of that was still sinking in. They were in very real danger here. Olly glanced down at where his hand was in Noelle's. He could see the shapes but it was like he couldn't focus on them. They were chameleons. He was glad the disillusionment charm had stuck, and he hoped it would stay that way. It made him feel better, even though rationally he understood the monster probably had enhanced smell and hearing and wouldn't really need to see them at all.

"Up or down? Olly looked to Noelle first of course, but then to the group in general. "Should we split up?" In small groups, of course. Nobody would be alone. Even so he was a bit nervous even for that suggestion. They were stronger all together, but they could cover more ground and search faster if they split up. Hopefully someone who was older, like a professor, had a more specific plan.
