[the Witches then explain the general timeline that Gon should expect, and he blinks, finding it a generous span for any exceptional bodily changes. he'd have plenty of time to ease through it, right?

what a grim thought, though. Gon didn't want to lose his body.]

It's okay, [Gon reassures both Killua and the Witches, and indeed, he doesn't seem worried.] I can just read about the different kinds of monsters that are here and keep alert for changes... maybe ask people what their earliest signs were. [[he's already been talking to monster people a little, anyway...

basically, it's Gon's nice way of saying this resource has met its end as something useful; as usual, they're better just doing the works themselves.]

Thank you, [Gon says politely to the witches, then turns to face Killua.] Let's go. You mentioned there was a library, right, Killua?
