Bellamy knew the only reason she could remotely think of him as nice was because she knew nothing about him. Gina thought he'd been a good man too, and now she was dead. But for now, as selfish as it made him feel, he wanted to attention and the connection that came with just hanging out with someone who didn't view him as a monster or a murderer. So he enjoyed the contact of her fingers lacing through his.
He offered Cat a sympathetic smile, giving her hand a squeeze, because even if she didn't say it, he was sure it was hard to be here without anyone you knew. Even if his group had their tensions, Bellamy knew it was better than ending up here on his own. "I know I'm lucky to have her here," he said, "But I've met some pretty great people here too." It was said in a tone that implied he was really only talking about her. Not the best attempt at flirting, and Bellamy wondered when he'd stop being rusty at it.
At Cat's question of whether or not Octavia liked Clarke, he gave a slight laugh. It was a bitter sort of amusement, because he knew the kind of tension that stretched between his sister and Clarke. "I don't know," he answered honestly. "She probably did at some point. Probably not so much now. Not after everything we've been through." Clarke had left Octavia to die, after all, and then she left them all completely. "But yeah, Clarke's the person I was talking about earlier. We used to be... partners. We led our people together, until we got separated." He shrugged and refused to let bitter memories ruin his evening.
"But we're all alive and we're all here," Bellamy said, not just to brush aside the reminders of resentment, but to remind himself of the good aspects as well. "And the relationship dynamics of my friends are nowhere near as interesting as my present company." It was easier to think about here and now instead of back home, especially when he had a pretty girl to distract himself and Bellamy made the decision not to feel sorry for himself tonight. "So tell me about you."
