Senku for his part, had his hands on his hips which wasn't unusual for him. If it was anyone but Gen trying to poke at his chest, they'd get told off immediately, and he'd move out of the way. As it was, Gen was the exception to nearly every rule he had, so he didn't move, he just let him touch him.

He was also confused, but he let his mind wander over the potential options. For one thing, Gen looked distressed, which means he thought something had happened to him. "Missed me?" He echoed slightly, brow furrowing.

"Ah." He said, as he came to that conclusion, that he'd taken some kind of injury in battle and it couldn't possibly be from Tsukasa, as he didn't take any serious injuries there, nor Ibara because the only injury he'd had was his arm. It was curious. When was Gen from?

"Two months." He responded easily enough. "Time here isn't connected to time in our worlds, from my understanding, time doesn't pass there while you're here." He wasn't sure about that.

"You've about confirmed it because I ten billion percent have no idea what you're talking about, except you think I've been injured by someone and I can't think of any reason you would think that. Meaning that you've existed in a time I didn't." He explained his conclusion. "And, presumably, I was there so it wasn't affected by my being here. Fascinating."
