Well...yes. Yugi had made that very clear, and then Atem had taken the puzzle away when he'd rescued them one last time, or so Yugi had said. ...and then he'd planned to chase him into the afterlife. But somehow he doesn't think they're on the same wavelength.

"I don't know what you want. The answer on my tongue is obviously wrong...but..."

We. Our.

"The two of you fused...souls?"

He just looks honestly confused. But he keeps talking, hoping to stall them. "In my world, Atem was partnered to Yugi. To my knowledge, they were separate...and after he left, yes, I chased him, because he'd left me without the chance to reclaim my title, and worse, without saying goodbye."

His expression darkened as it all sunk in. Because he really tried not to think about this particular incident most days... "But I was wrong. I risked Mokuba's future for my selfish desires...I risked everyone's futures, because I couldn't let the past lie. I fucked up. And I don't have the power to divine who you are...but I'd listen."
