SG-1, Daniel/Jack, Sam/other (possibly), Daniel is in love with Jack, but is convinced Jack loves Sam (and that Sam loves Jack) and since he wants his friends happy, he decides to help them admit their feelings. He talks to Teal'c who agrees and tells him about some Jaffa love drug which will make lovers admit their feelings. They manage to sneak the drug into Sam and Jack's drinks, but to their surprise Jack then admits his true feelings - for Daniel! Sex ensues. If you want, Sam admits her feelings for someone else (or Jack, but I guess she won't get any then). You can then have Sam and anyone have sex, just not Sam and Jack!
