and here's one for the jack clones,
how about:
there's an alternate reality and jack is a mechanic / weapons specialist CIVILLIAN,
or we coud take him up on his suggestion in point of view (that there's another "me" [jack] out there who understands whatever your talking about, (sam talking about alternate realities) but he must be a civilian),
and "his" sam died / was killed by goa'uld. Our sam spends weeks without sleeping trying to figure out a way for the other jack to stay (like she does in a hundred days), she succeeds (as always) and he does stay, and coz he's civillian, they get "attatched".
there could be some really angsty scenes (like in the end of point of view -- the kiss) with our jack watching over our sam and the alternate jack make out etc,
whaddya think?
