Spoilers, duh.
So, for the most part, I understood this series perfectly. Everything fit into place, everything made sense. More or less, that is, but I was satisfied.
Then Abe meets his past self, which causes a time paradox, ripping the universe open so aliens could invade. Fine. But then... He charges one of them, kills it with his telekinesis, and all of a sudden they all disappear. That's the part I'm having trouble with.
Logically, destroying himself at that point wouldn't matter, because the paradox already happened, and the damage was already done. And even beyond that, how does killing one aline cause all of them to die/retreat? What the hell was that about?
