If he knew she felt that way he'd be the first to tell her it was fine. He still had habits from his life that made him feel like an ass for not being the most trusting person. What mattered is that it kept them safe.
He didn't feel that tension around her, despite her paranoia. It didn't feel like her eyes were on him in fear or anger. She was refreshing to be around. It wasn't that his friends hadn't forgiven him, a bunch of them had, but he worried about some of the rest of them. He noticed her gloves but didn't think too much of them, they all had their quirks and maybe weird out of season clothes was hers.
A flicker of surprise crossed his face as she met him with a smile, he'd been hoping she wasn't looking. "I'm Isaac" he didn't offer his hand or anything but the corner of his mouth did twitch in a brief smile. "You're new?" he asked knowing she had to be and then looked around the tower before rubbing his hand over his hair "I hope you're a good shot."
