I don't think I read that particular one. I think it was actually mini!Jack's decision to go to high school in the show, although that's very bizarre and suggests that there weren't a lot of other good options. We've heard no more of him since, and the Jacks kind of decided not to keep in touch (although in my mini!verse, they have to, sort of, since the clones have to get medical check-ups at the SGC. Because they totally would.).

Rascals was AWESOME!! Man, I love that one. And all the kids were really good. And Alexander got to do something productive rather than cause trouble for Worf!
