"Cool." Griffin dips his chin, hands busying themselves in freeing the telescope from its secure spot. He spares a passing glance at Hero's spread, but, despite also studying Divination, has no clue what any of them mean. If he had to guess, he'd say they're about to to a farm, where they'd find the remains of a shipwreck. Which seems statistically unlikely. Which is why Griffin usually keeps his mouth shut in that class.

Once the telescope is liberated, he adds, "It's pretty dark here at the campsite, so we shouldn't have to go far at all." There's an implication in the words Griffin decides to stress. It's very good that there's a prefect in this tent.
