His brow furrowed at the idea of people with powers, but only slightly. Prior to arriving here, that might have seemed completely impossible and even crazy. But then, people here had powers. He even could use the Force. Bellamy thought of pointing that out, but then remembered the warning that people who could use the Force might end up targeted. Cat didn't seem like the type of person who would do something like that, but maybe other people here might overhear. He didn't want to do anything that might put his sister, Clarke, or Raven in jeopardy. He was distracted from that train of thought with the revelation Cat's mother had been murdered and Bellamy's expression shifted into one of sympathy and understanding.
"The good guys killed my mother too," he admitted, because he didn't have a problem confessing that and because he hoped it might make her feel better. "Well, they thought they were the good guys at the time. And no one had powers where I'm from." It was a dark train of thought to go down, one that still made him angry. Not just because the Ark had such cruel laws, but because his mother's death was equally his fault.
Cat shifted though, leaning forward and Bellamy hadn't been able to help the way his gaze shifted downward as well. It proved to be just distracting enough that when she reached up and placed her hand over his, he was able to easily abandon the darker thoughts of loss back home.
"You're right. It's nice to talk to someone who gets it. My... friend wants to get involved with the Resistance," he admitted, delivering the news quietly because even if he was angry, he didn't want anyone targeting Clarke. But it seemed like most of the people around here actually more interested in supporting the Resistance than working against it, for some reason. "I tried to tell her that we just need to worry about us, but," he shrugged. "What's the point of getting out of one war only to get right back into another one?"
