FIC SEARCH: McKay/Sheppard

[little-lilac.livejournal.com]

hi..uhh... I'm looking for a fic I read not long ago and I think it's pretty new but I can't find it!

John is jealous of Lorne, because he thinks Rodney is in love with Lorne. John and Rodney sit in the mess and Rodney talks something about wanting to uhh... hit on a military man. Whatever. And John thinks it's Lorne.
Sometime later he watches per video how Lorne gives Rodney training in... something... shooting?!
John becomes jealous and storms into the room but Rodney is alone and they finally get together and everyone's happy and I wanna read it and I don't know where it is...

Does anyone know what I'm talking about?
