Well, Komui apparently hasn't caught on to what's going on yet, but I fear that Allen and Rabi might never be able to go back to the HQ ever again... =P Especially after all the contact - Rabi seems the type to tell Komui about it, ne~
Everyone has blood in Rinari's dream - at least, Kanda and Rabi seem to, and Crowley probably does. I think it just means they're badly (internally) injured. I think Tiki might die at the end of this arc, but only if Rinari kills him, since I don't think Allen will (and Road won't/can't die yet).
Bookman, Miranda, and the others are just hanging out in Japan. XD
