Billy followed after Mark, but it was a hesitant, stumbling pace. He looked back at Roger, wanting to just stay and listen. It had been far too long since he'd been able to just sit and listen to other musicians. But he really did need to get back. It was with a reluctant and heavy heart that he crossed the threshold and let Mark shut the door.

He busied himself with putting his sunglasses back on, more to hide his eyes from Mark than anything. He could mask his emotions easier if half of his face was obscured.

"It's not any easy thing to say," He said with a small smile. "But if you could get it, I'll bet a tape of his music would be a great way to say thanks. I'll even make sure it gets into the right hands to get to CHAOS. I'll bet he'll love it." His smile grew strained, almost awkward. Like he didn't know what he was saying. But really, he was struggling to hold everything in. Holding himself back from hugging Mark the way Roger had hugged him. Resisting the urge to insist the immense thanks should be going the other way.
