Maybe she was losing it. Maybe she was just excited. Either way, Diana with a fit of giggles was cuter than it had any right to be. It was a nice change from the morbid conversation. In an attempt to silence her, Thor did kiss Diana's forehead ever so gently, her face in both his hands for that second, before he looked back at those beautiful dark eyes. Even two days deep into post-boyfriend-murder ugly crying, Diana was exactly as radiant as she'd joked she was. He couldn't deny that and didn't want to.
"So... Now that I am back, what do we suppose we should do about... well... me? If there's another me to do anything about, I suppose I should say." He didn't think there would be though. Something told him, based on the huge scar, that he was still himself. Just the one body and mind. Not like Loki, who could be whoever they wanted at a whim.
Thor only knew one thing though, in the moment. He'd missed time he intended to make up for.
