If the events that occurred with Lotor had never happened, Keith would be dead.
If Lotor had never found out about Narti being a spy and killed her, he would have never run away.
He would have never become the enemy of the galra empire. He would have never been betrayed by his generals. He would have never escaped zarkon and he would have never been in the place he was to hear the galra’s plans to blow up Naxzela.
