<I can come up with a few reasons. I don't know when it started, but he's always had this sort of resentment towards the City. Since D1 when we came to the Queen asking where the Black Garden was. He's a bit of a dick from the get-go. Then we come to the Battle of Saturn. He witnessed his entire fleet get wiped out by one dude. He's probably confident that Mara's dead. What was her external plan? Help us reach Oryx by clearing his fleet. In his eyes we are probably responsible for the deaths of hundreds. Also he may be insane thanks to those hundreds of deaths.>
