Heres another one for you (& yes I know a lot of people don't like this sub plot (for obvious reasons)
buuuuuut.... what if Darth Maul was Sifo Dias
he makes sure he has a very public "death" & then goes into the shadows & removes his make up to reveal the tattoo's underneath (a la The 89 Joker)
So he can contact sideous from Camino and tell him the clone army has been ordered (easily done as his voice is practically a grough whisper anyway
