***I'm not entirely sure myself. But what I do know is that these men and women actually, are the ones who hated me and Rachel when we lived here. They were the ones always trying to kill us.***
Joseph: You four are mutant Dual-Changers. You were born in our lab beneath the city to Dual-Changer parents. We took you to do tests on you like everything else that we own down there.
Rachel: You don't own us!
Joseph: Yes I do. Now keep your mouth shut and let me finish! The tests we ran on you failed, or so we thought at the time, so when your parents died, we let you go. The same thing happened with your 'pets'. After we let them go, my son was going over the tests, and realized that they did not fail, and that you were dangerous monsters. We tried to kill you two, Melissa and Rachel, but you escaped. Jake then decided to track your little 'pets' in order to find you.
Jake: I was mad at you for escaping, so I decided to find you by following the mutant cats.
