2nd Indigo Child?
(spoiler)
If you lose to the AI during the end fight, you see an ending that has Lucas say something like the voices in his head tell him his unborn child is the next Indigo Child.
My question is this: If the first indigo child gave the "answer to everything," what the heck is the 2nd indigo child supposed to answer?
Until that moment, i was under the impression that the birth of the prophecised indigo child was a sort of one time only thing. Like, most good prophesized saviors;)
Nonetheless, i think the safest thing to do would be to kill all of the indigo babies so that the ever-so-evil purple guys, and the glowy AI guy can't use 'the secret' for their evil gains.
