Major Lorne (and Rodney maybe) get thrown through the Gate and have to find a way home to Atlantis. Heavy Lorne (and Rodney if you put him in), with a lot of Young too. Not phased if it's slash or not.
Doctor Who/SGA Crossover. Rodney's really a Time Lord (either The Doctor, Master, or an Unknown), but is in Human Form, & doesn't know. Does he find out? John gains immortality/near-immortality with the help of a Ancient Device; J/R Friendship or Slash. Have Fun! Anything Goes:)
