Yu-Gi-Oh!, Season 4: Waking with Dragons

[at the train station]

Téa:
How this train ride anyway?

Joey:
Too long.

Téa:
[sighs]

Duke:

Tristan:
Duke's right. Plus he's gonna keep an eye on Rebecca too.

[Flashback to Rebecca and Arthur see Pharaoh and his friends leaving]

Rebecca:
I wanna go too! They need a brain like mine to figure out how to save Yugi! Please!?

Arthur:
It's too dangerous. And the Pharaoh has enough on his mind already.

Rebecca:
Huh?

Arthur:
The last thing he needs is the responsibility of looking after you. His closest friend in the world's been taken from him.

Rebecca:
[cries ran back to the caravan] You don't understand anything, Grandpa!

Arthur:
Rebecca, wait! It's for your own good!
