Jeremy, Aelita and others in “Unfinished Business”

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.

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

Well, go on. Tell us.

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

We already knew that.

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

Really? What became of her?

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

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

No. She stayed on Lyoko.

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