In her defense, Claire had tried to stay mostly quiet for Simon's sake. Because if she opened her mouth to try and talk to him, she'd end up changing hats and going into psychiatrist mode. She did feel badly for Mal, though. Going stir crazy wasn't his best look. And she knew how stressed he got when his crew was in danger.
And, of course, they all missed Wash.
When Mal finally snapped, she glanced back and forth between the two men and nodded understandingly. This was between them. She was the third wheel. She stood and gently kissed Mal's cheek. "I...will run get dinner, how's that?" She flicked her tongue over her lower lip. "How about you boys talk while I'm gone, hmm?"
Simon barely even noticed the redhead exiting. He was happy for Mal, looking almost domestic and all, but he couldn't form actual words to say so. Especially knowing what he did. Knowing his own relationship, screwed up as it had been, was already ruined. Knowing his own little family was gone. He hadn't even had time to mourn losing River properly, he'd been so focused on trying to fight the demon who'd taken him over.
And worst of all, he was the reason Wash was dead. He'd killed his friend. Yes, logically, he knew he hadn't done it. The demon had. But that didn't stop the glaring memory of snapping Wash's neck, of the demon's laughter at taking the woman Simon so pathetically loved. And he was, wasn't he? Pathetic. This was pathetic, this practically catatonic state he was in.
But he couldn't make himself pull it together.
As Mal quite literally threatened to beat him, Simon only shrugged and rolled to face the other side of the room. The only reason he'd been facing the direction of the tv in the first place was because Mal watching Disney movies was hilarious and it almost made him smile.
