"We're goin" inter the Forest," said Hagrid implacably, ignoring this threat entirely. "Aren" no werewolves, but there's plenty what's dangerous in there, so yeh stick close t'me, yeh hear?" Then, as Ron and Draco had a very stressed-out and silent contest in which they each tried to pretend not to be as scared as the other, he explained about the dying unicorns, and what they were looking for. The two first-years in his charge exchanged frightened glances, and then realized what they'd just done and glared at each other instead. Evidently, neither could figure out how to complain about this without appearing frightened, so they ended up saying nothing. Nervously, they followed Hagrid into the Forest, with Fang ambling along behind them.
