Rebellion was brewing within the walls and when sh*t hit the fan, who would be there to dispose of his troublesome comrades he'd known all his life and mop up the mess? Definitely not him, so he wasn't going to leave any room for that situation to occur. And if his brother was lost to the rebellions...he wouldn't forgive himself when he could have done something about it.

"I'm glad you decided to come with me. If I got to choose who to start a new life out here with...I'm glad it's with my little brother."
