It has been six months since your last battle with Eggman that left you (as Tails) effectively brainwashed; instilling a love for diapers in your mind, squishy diapers espcially, rendering you completely incontinent, and your speech completely babyish, but leaving the rest of your mind intact. Sonic had sued Eggman into oblivion after the accident in hopes that there was some way to reverse it, and won millions for your care; unfortunately for you, it had come to light that the brainwashing ray was designed to be irreversible, and much worse than how you were effected.

Sonic walks into your room to check up on you, and sees that you're sitting at your desk, trying to design something to help in your care. You're wearing one of your bright pink diapers and have a cute Sonic pacifier in your mouth. You don't even notice Sonic come into your room until inspects your diaper further and see that its wet. He knows though that you're prone to having accidents because you lost your potty training, not that you even remember you ever had it in the first place.

Sonic: "Aw, Tails. I already told you that Eggman said the effects of what happened was irreversible. so why do you keep trying something that you know will fail?"
