Reposted for clarity
I'm an outsider to that scene, which I'm not finished reading... but I understand what you're saying about L not being rescued. If Frank knows what's going on he kind of has to say something, but I can add an OOC note to the post making sure nothing happens until Ryuzaki comes back I think? (i.e. people will ask questions or make plans but no one will start a thread rescuing him?)
[Frank's going to feel just awful though, and want to be nurturing in his incredibly awkward way, even if he doesn't know the details... which is not the important part here, but all the same he is.]
Anyway, at this point I'm going to wait and have Frank post when the mod says to.
