Hey, this episode of Yugioh has Yugi's mom in it. That's a surprise since we pretty much never see her at all. As much as Joey's mom or dad. And of course, where or who was/is Yugi's dad.
We may never know though. I'm guessing it would be Grandpa's son. It's the hair.

I think this is the ONLY episode she was actually in, & of course got cut out of in the English version.

And that's the only reason why I mentioned it.
