The Ties of Friendship

At the beginning of the episode, Grandpa was telling how he met Arthur, and the camera will show the duel, and you can see that the Millennium Shield was in attack mode, not defense mode.

When Rebecca used Stop Defense on Yugi’s face-down defense card, a second before the card flipped, Honda exclaims, “She’s forced the Dark Magician into attack mode!” How did he know what card it was?

The Ties of Friendship card only exists in Japan.
