"That's new. Care to explain how you got your hair so long, Mister?"
Jon looked perplexed. "Uh…" Curious, he slowly moved a hand to his chest. "Huh," he noted.
"What's going on?" asked the uninformed Colonel.
Jon grinned. "I'm cured." As he said it he realised the 'problem' with his voice was that it was back to normal.
"Cured of what?" Jack pressed.
Jon glared at his original. "None of your business. I'm fine, so you can get back to doing your job." Obviously the recently-minted teen was still struggling to accept that he had been kicked out of what he remembered as his duty – saving the world.
"You may be yourself again, but I still need to give you a full physical to determine what happened, why it happened, how to prevent it from happening again, and whether there is any lasting damage," Janet explained.
"Himself again? Who was he?" Jack questioned.
"Colonel, if you'll give us some privacy, I can begin the examination. Unless you want one yourself…" the CMO threatened.
"Fine," Jack conceded a little sulkily. "I'll go see what Carter's doing."
Janet waited until he was out of earshot and announced, "I'd better fill Sam in before the Colonel reaches her. Back in a moment."
Jon nodded. "You do that."
A few minutes later…
"Carter, what's going on?"
"I'm plotting the decay curve of the…"
"You know what I mean."
"If you say so, Sir."
"It's not up to me to tell you, Sir. He doesn't want you to know yet, and you don't need to know."
"I'll need to know how to deal with it if it happens again, Major."
"There's no danger, Sir. Apart from his embarrassment."
"Does Janet know that for certain?"
"Sir, wait until she's fully examined him. If she decides you need to know, she'll tell you. For now, there's nothing to worry about."
"Doesn't stop me from worrying," Jack grumbled as he left.
Later, in the infirmary…
Janet shook her head. "I can't find anything wrong with you, Jon. Not a scratch, apart from the one on your arm." She said the last phrase with a hint of questioning.
"Neighbour's cat," Jon briefly explained.
"In your initial blood work, your hormone levels were slightly wrong, consistent with your recent transformation, but they've dropped back to normal levels for your gender and apparent age. There's no sign of a probably cause."
"Am I good to go, Doc? Or do I have to wait for Thor to scan me too?"
For now, I'm releasing you, but I want you to call if anything else unusual occurs, and I will call you back in once Thor shows."
John sat up on the side of his bed and began tapping his foot. "I just hope he can be convinced not to beam me out of school. That would be awkward to explain," he understated.
"Quite. You're free to go now, but remember to call as soon as…"
"Got it, Doc. Uh… how do I get back home?"
