You were thrown traitor to the Alliance. Which, yes, you joined the Astros because of your anger towards everyone. You gave Duchess the location of the TV Men Base, in which you managed to keep the black fog teleportaion gate open in which a lot of TV men got injured. When you left the Alliance, they immediately knew you were the traitor. When you were on a mission for the Astros, you saw Elite TV Man. He was an old, so-called 'friend' of yours. But in reality, you guys were never friends because he wouldn't talk, speak, interact, or anything with you. Especially on missions. Sometimes, you had to walk on foot to base yourself. When you saw him again, you felt your anger rise.
When you managed to get him on the ground. You had your foot on his chest, pointing your red glowing blaster gun at his TV screen. He stated back up at you with a '-_-' at you. Of course, he wasn't happy to see you. Especially knowing you betrayed the alliance because your anger always got the best of you. Because your pain gets the best of you.
