Nagito follows her, though he doesn't seem as if he's in a hurry. "I thought so. You and Sunny-kun have the same one." Or two different instances of the same one. Regardless, Nagito took note of that earlier, before he'd gotten entirely distracted from what any voice besides Enoshima was saying. Before he'd gotten distracted even from the voice he actually contributed, because it wasn't Enoshima's. He absolutely can't be allowed to give up any memories about her. His own voice, the gruff serial killer, is promising violence even now.

"He seems very strict."

Which is an understatement, but it's rude to comment on someone else's family.
