Of course, that applies to Sunny too, but Nagito remembers his own state after the Crossing--he'd been exhausted. So maybe emotional exertion still works.]

And, of course, we could always ask Ferryman-san if we have to. [Though Nagito thinks it's probably better if they do it themselves if they can.]
