He had forgotten what her laughter sounded like; they'd only been apart about five months, but to Mohinder, a world of things had happened since that time. Betrayal, love, hate, a personal war. He'd almost lost his life. He'd been depressed; he couldn't contact the other evolved humans any longer as he felt he'd betrayed them. He was glad though, to hear Nathan and Peter had made it out of the Pinehearst fire unscathed. It seemed though, during that time, no one had really remembered about him. He got himself out though, that was what counted.
He himself can't even believe the elated feeling that washes over him when the young girl launches herself over the sofa, arms wide. Accepting. No one to say 'you used to be a monster, I don't trust you any longer'. Molly didn't know of any of that. It was for the better.
He puts his bag down and kneels so he can accept the charging hug, Molly nearly knocking him off balance, and the first laugh in months is elicited from the young scientists lips. "Oh Molly." He mutters, hugging her tightly. "I'm so happy to see you." He pulls back just a little, his arms still on her shoulders. "You're just as I remember you." And he was glad he would be as she remembered him, too. No scales, no lesions.
