Once he gets high enough, he starts to look around, calling down to the others.

"There's a thicker grove about ten minute's walk that way," he offers, pointing in one direction before pointing to another. "Or a cove that seems to be a monster nest about five minutes that way - easier to defend, but we'd have to clear it out first."

He keeps looking, something about this entire thing gnawing at the back of his mind.
