Gwen Tennyson, Young Ben Tennyson and others in “The Forge of Creation”

Look at me Ben, you recognize Kevin. You must know who I am.

[Thinks for a moment] ...Dweeb, what happened to you?

Puberty.

You have travelled in time. That's Gwen, that's Kevin, and... I'm you.

Please. I would never turn into anything THAT lame.

[NRG changes to Ben] I'm you, 6 years later, and Kevin 11 is a good guy now.
