1) The one where the first time Sam uses the Goa'uld ribbon device it scrambles her neural pathways and leaves her without access to the linguistic portions of her brain for a few days, and the team has to find a way to bring her through it.

2) The one where something goes horribly wrong with Sha're's pregnancy, her body absorbs the Harcesis, and Amonet goes into a Goa'uld coma, leaving Sha're with the genetic memory of the Goa'uld and a position of power in Apophis' empire, and ends up becoming a fake System Lord/replacement main character for Absolute Power.

3) The one where Hammond comes in to the SGC one morning only to find that SG-1 has taken over the place and are playing some weird four-faction game of cat and mouse because one or more of them is under alien influence, but no one is sure who.

4) The one where Sam and Daniel fall through the Rift into S1-era beyondtherift and get dragged into Torchwood Chicago for three years before the Rift establishes a two-way connection back to the SGC, where only a few months have passed, and Jack O'Neill and Jack Harkness eye each other a lot and are quietly mistrustful because no one should get that close to/have that much power over their people without them knowing about it. (Okay, this one I have bits written out of in my braintics file, but come on. IT WOULD HAVE A READERSHIP OF ONE PERSON. ME.)

5) The one that comes before Scales.

[ETA] 6) The one where they discover a dialect of Goa'uld which exhibits rhyming slang and Daniel just doesn't want to explain.
