For an instant, his eyes took sight of her blonde hair and his mind immediately told him it was Clarke. Bellamy's breath hitched in that one instant and for a fleeting moment, he looked at Claire as if he knew her. But the very next heartbeat, it was gone. His brain caught up. She was shorter, her hair and her complexion darker. No blood or bruises or scars. Clarke was gone anyway. She left them all behind. But wasn't it fitting that the one person he managed to meet up with first in this place also managed to look like the one person he had been most devastated by back home. What great luck.
"Hey," he greeted her gruffly and, after a beat, managed to flash a belated slight smile. Bellamy didn't want to look too preoccupied or tormented - the last thing he needed to reveal was the fact he just committed genocide. He couldn't imagine a scenario where that would go over well. His own people were going to hold that against him - Jasper at the forefront - so he couldn't expect strangers to be a-okay with a mass murderer right out of the gate.
"Sorry if I'm a little skeptical," he folded his arms across his chest. "I'm a little outside of my element here," Bellamy shrugged one shoulder. She didn't look like much of a threat. But then... neither did Clarke, or Raven, or Octavia. Neither did Lexa. And hell, neither did this place. But Bellamy wasn't willing to let his guard down, even if he was making an effort not to seem quite so grumpy to Claire. He had been colder to the local that found him.
