It's a good thing Waver explains the Void Cryst, as, once mentioned, Yin was going to ask about it. She listens carefully, eyebrows furrowing, slowly and slightly.

"Is the cycle going on, now?" Otherwise, she might need to ask what happens if the world they're currently in cycles with them present.
