Ben 10: Alien Force, Season 2

Gwen:
Leave him alone!!

Highbreed:
Very well. I was nearly done with him anyway. (Gwen creates a magenta shield, but the Highbreed shatters it) That won't keep me from you, vermin. Or perhaps I'll finish off your boyfriend first, so you can watch him suffer. Yes. You're no threat to me now.

Gwen:
(enraged) I said…LEAVE HIM ALONE!!!

(takes on her dormant pink-and-purple Anodite form and blasts Highbreed away)

Kevin Levin:
(regaining consciousness? Gwen!? (comes to her and puts his hands on her shoulders)

Gwen:
(deeper female voice) So much power!

Kevin Levin:
Gwen listen to me…you gotta shut it down!

Gwen:
No! I think I can defeat the Highbreed all by myself!

Kevin Levin:
Your grandmother said that it will take at least 75 years to master all of that power!

Gwen Tennyson:
We don't have 75 years!

Kevin Levin:
You'll lose your humanity. You won't remember Ben or me. Ben will find another way to win. You got to come back to me, Gwen. I just can't lose you, okay?

Gwen Tennyson:
(reverts to her human form, opens her eyes) OK. (smiles)

(Kevin smiles and the two passionately hug)
