Tossing in the Kamen Yaiba and the two dead bomb squad guys kinda confuses it to me... Cause, dude, they're dead. They're not going to suddenly come back to life.
.... are they? o_O

They could do a Simpsons thing, just scroll by the characters.

Hmmm... Maybe Yukiko from her actressing days? She retired cause she was preggers, didn't she?
So it's all Shin'ichi's fault she quit! *Cackles manically*
Or maybe Yikiko's sister... hmmm...

Or Heiji disguised as Vermouth on a motorbike?
