The sreen displayed "46 minutes remaining"
Jeff knew what that meant. The transformation had been set to last only one hour, after which Johnny would automatically revert back to his "Real" self, back to being Jenny. He notices the boy had come next to him, put a firm hand on his arm and was looking at the screen as well, in confusion apparently!
"What is this thing, dude?" Johnny asked.
Jeff was a bit surprised. Doesn't he remember? "Honey, it's the chronivac, remember? I...used this just a little ago to make you into a nice handsome boy..."
Johnny scratched his lightly bearded chin, eyes squinting, puzzled look on his young face. Then his expression change to that of realization. "I... Oh. I remember now! Oh man, Jenny! I mean, me... That's who that Jenny was, she's me... I'm her, I mean I was! Woah"
"Yeah... that's right. Weird that you forgot for a moment there... Must have been the mental changes that came with the transformation, or maybe even just the testosterone. Anyway, so you remember now? Who you are?"
"I...do. I remember being a 25 year old woman, being your girlfriend, I remember coming over earlier and the machine... I remember not liking you making me a schoolboy and begging you to change me back"
"Yeah well, see look at the screen. It appears youll be changing back to normal in 43 minutes... So yeah problem solved I guess, Jenny."
"What? Oh man... Jeff I don't wanna change back! I'm not Jenny, I'm Johnny now! I remember everything but I'm not her anymore! If I change back I'd cease to exist, Jeff please I don't want to die! Please don't let me die!" The boy was now sobbing and grasping to Jeff's arm desperately. Jeff became distressed, what the hell should he even say? This has taken a dark twist!
"Johnny, please try and calm down... It's not like that. You wouldnt die, the chronivac made you... You're actually Jenny remember?"
"So what if I was made this way Jeff, you made me, I'm a real Person now, I have feelings, I want to live, please!"
"Oh dear... You're right I guess. This is fucked up. But what about Jenny then? If you live doesn't that mean she'd be the One dying instead?"
"No Jeff she's still here in me, in a sense I am still her but changed, I have all the memories and everything! But if I'd change back I would just be erased completely!!"
Jeff thinks it over and realizes it was true. He realizes he will have to make a tough choice... On the one hand he lets the timer reach zero, Jenny getting restored to her real self but erasing Johnny. On the other hand he could try tempering with the chronivac and try to keep Johnny the way he is now...
