The friendship between somebody who works at the SGC and somebody who works at NORAD. NORAD thinks that SGC works at a job that's similar to his/hers: highly classified desk work at the Mountain, with the only excitement occasional drills.

Somehow, the original Stargate translation team manages to open the "Doorway to heaven" without Daniel, and avoid killing the Abydonians (AKA, everything goes more or less the way it did in canon, but with even more translation problems--maybe the military people are really good at Charades, or something). And then they head out into the galaxy to fight the Goa'uld, but with tons of comedy moments because their translators aren't Daniel, or even Daniel-trained.

Back in the day, Methos was Egeria's host and the catalyst for her change of heart. Post-Horsemen, even though that means changing the date that they rode, so he knows the temptation and appeal of power and has gotten over it.
