Just starting a random highly speculative thread:
Now that the Vodoo Lady has what seems to be the remains of LeChuck, what does she need them for?
I don't buy into the theory that she's evil, but like most MI characters she seems to have her own agenda.
My first guess is that she might be after the Secret of MI itself - and she needs LeChuck to get there. And it's got to do something with monkeys. Someone in the forums observed that Galeb is an (ex-)monkey which I think is an excellent observation and explains why he knows so much. Does she need LeChuck to control the monkeys for something?
Anyone feel like throwing in some wild speculations?
