Introduction: "Fragile Balance" occurs just as it does until we reach the scene where Thor states that he is not sure he can cure Young Jack. Here is where the fic diverges from canon...Instead of being able to cure Young Jack directly, Thor needs to create another clone to monitor it's growth so he can determine exactly what he need to do to cure Young Jack.
: In order to stablize the adolescent O'Neill's genetic structure, I will need to use Loki's equipment to create another clone so that I can monitor it's development and isolate what gene sequences need to be repaired, and how to repair them.
: Whoa! Hold on! You mean there's going to be two little me's running around!
: If the procedure is successful, then yes, both of your clones will survive and live the average human life-span.
: C'mon Thor, isn't there something else you could do, anything else...magnets?
: Without a frame of reference it would be statistically impossible for me to know how to repair the flaw.
: We're talking about my life here...
: [interrupting] Thor, does the clone have to be of Colonel O'Neill?
: What are you suggesting?
: Clone me.
Both Jacks look up in surprise.
: If you implant me with the same safeguard that you placed in Colonel O'Neill's genetic structure, and then cloned me, you should be able to use that information to save Colonel O'Neill's clone.
: It is possible, though the individual is different, human genetic structure similar enough on a basic level that I should be able derive the necessary information from your clone, Major Carter.
Carter looks up at Jack with a soft, knowing smile, waiting for him to respond. Jack suppresses a similar but almost envious look on his face. Young Jack make little effort to hide the fact that he is pleased. Jack nods in approval.
: Okay, let's get started.
Cut to van scene outside of the high school...this takes place much as it does in canon, but with Jack and Sam in the front seat, and Young Jack and Young Sam in the back.
Whoever adopts this bunny can add the farewell dialogue.
As Sam and Jack drive away, Young Sam and Young Jack look at each other and smile. To the same soft fade-out music they played at the end of "Lost City," we see Young Jack and Sam walk away.
Jack's hand slowly moves toward Sam's. Their fingertips find each other and then we fade to the credits.
Now someone adopt this bunny so we can find out what happens to Young Jack and Young Sam.
