You keep using that word, "always". You understand this has a meaning only in temporal context, right? The narrator sequentializes the events in order to make them comprehensible, but that doesn't mean the Egg actually lived these lives sequentially on by one. Once you realize that, your argument about "always" disappears. Also the question of free will becomes much stranger than you put it. Imagine you filmed somebody and watching it later. Does the person on film lack free will because you can just jump to any place on the film and "predict" his actions? I think you won't make this conclusion. Imagine now somebody who does not perceive time linearly (we're in SF territory so we're allowed to). Would his existence mean free will does not exist?
