(referring to Dravek attack) Thanks for saving me back there... again. This is a huge thing: a sign of personal growth. Proof that underneath it all Highbreeds aren't so bad. That despite those terrible things you may have said before, you really do want to try to be friends with a human.
What is with you? Yeah, you don't like the alien creatures I turn into - I get it! - but, come on, I was saving you! Cut an alien-monster-guy some slack once in a while.
It's weird. Despite the fact that I don't trust you any farther than Humungousaur could throw you, it's still pretty cool how we've managed to work together to survive. I mean, we may not be friends exactly, but we're not full-on mortal enemies anymore either.
But we've been able to see past our differences, probably because I know what it's like to be - well, not a HighBreed, EXACTLY - but a whole bunch of other kinds of alien creatures kind of like you. (indicating the Omnitrix) Thanks to this, I get to walk a mile in other life-forms' shoes, so I can totally understand what it's like to be them since... I HAVE been them.
You and I are more than mere enemies. Highbreeds were the very first race in the universe. All species hence, other than pure-blooded Highbreeds, are nothing but mongrels, hideous abominations of nature - especially humans. As soon as I no longer require your aid for my own protection, Ben Ben Tennyson, I shall eradicate you, and there will be one less vermin infesting a grateful universe.
