Jeremy, Odd and others in “Unfinished Business”

I can explain everything. All this kissing is another one of X.A.N.A.'s schemes.

That doesn't make any sense. He can't control us.

I know. But I also know I did not kiss Heidi. So there must be a Jeremy clone somewhere.

And a Yumi clone.

Ulrich

And an Ulrich clone also.

That's right. And I bet they're all just one polymorphic clone.

A poly what?

A polymorphic clone. It can change its appearance at will. X.A.N.A. must have sent some kind of ghost that can look like anyone it wants to.

Ulrich

But why?

To make trouble in our group, to divide and conquer.

Ulrich

X.A.N.A.'s really smart. Not like us.
