Code Lyoko, Season 2

Jeremy:
Franz Hopper was the creator of X.A.N.A. In his diary, he wrote down everything that happened during the creation of Lyoko. Everything.

Aelita:
That's means you'll be able to find the anti-virus.

Jeremy:
Yes...it does. But there's something more.

Ulrich:
Well, go on. Tell us.

Jeremy:
Well, before Franz Hopper virtualized himself on Lyoko, and before being taken prisoner by X.A.N.A., he lived here on Earth.

Yumi:
We already knew that.

Jeremy:
Yes. But what we didn't know was that he had a child, a little girl.

Odd:
Really? What became of her?

Jeremy:
He virtualized her on Lyoko at the same time as himself.

Yumi:
And? Did she fall victim to X.A.N.A. too?

Jeremy:
No. She stayed on Lyoko.

Aelita:
But that's impossible! If Hopper's daughter were on Lyoko, I would have definitely known that! I'm not...?
