I lean towards the Nekomata prompt, if only because I'm still fairly early on in FFXVI? (I'm at the part where Clive, Jill and Cid are on their way to the Mother Crystal, and then, you know, sidequests happen because Clive is just such a nice guy who has to help everyone). That might be the way to go.

Since they will be both sleepwalkers though, it might be a chance to help each other out, or stage their own rescue.
