Both NC-17 and so links to wraithbait.
Summary: Sometimes you miss the thing that makes most sense, and in this case she certainly had. But now she could see and that was all that mattered. McWeir UST/smut.
Pairings: Odd mix - McKay/Heightmeyer, suggested Shep/Weir and angsty McKay/Weir UR/UST
Spoilers: Small ones for Brotherhood, The Seige and vague early season 2 spoilers.
Summary: Set after the Seige. A veritable angst fest - very raw and quite screwed up but still McWeir.
