Lemur nodded but it looked a little stiff and sort of terrified. Finn wasn't frightening but he wasn't sure how to react to people anymore and he was worried about screwing this up. If Finn was being kind to him then he didn't know how to react. He'd be on more solid footing if Finn became angry at him, but that would mean he'd done something wrong and he didn't want Peter to regret bringing him to this place, away from where he'd been.
He watched Finn set his needles down and was a little comforted by that, although he was still tense and remained hiding behind the sofa, his finger beating out a rhythm of three over and over. "I, I think so." he was going to end that with a 'Sir' but he knew he wasn't supposed to. "Thank you." he added.
