I think a Hakuba or Kaito in camp would make me delurk into audiencing. (Have been too chicken to, really.)

So, humm, Kaito in the US? He'd probably go as Kaito and pretend for all the world to see that he was not in any just coming along for a gem/man in gray/whatever. (So yeah, I see him apping as Kaito, not Kid.)
Maybe a school trip? Something else?
Wait, what was that case where he went with aoko to go diving? (The submarine case?) Perhaps that could be used as a lead... Hm. Dunno.
Or maybe he's off to visit Aunty Chat Noir and dropped by on the way? >cD
Or a magician reunion? *shrugs*
