They were definitely one of my first pairings outside of McShep. SGA was the first fandom (I had already been obsessed with several other fandoms for a few years) however SGA was the first and to date the only one where I started the show from the beginning at the same time I started reading fic, and eventually writing in the fandom.
Usually I’m a late start, and start a fandom after it was cancelled or its been on for a year or two. With SGA it was different and holy crap McShep ♥ still do, and quickly immersed myself in the fic. There was SO much, but by S2 I was craving a little diversity- then Runner aired HEE!! & I had two new beautiful characters to drool over: Lorne and Ronon Dex.( a few pics )
To be honest I’m not sure which pairing came first Lorne/Sheppard or Ronon/Rodney, but they were initially my preferred pairings to separate Sheppard/McKay. It quickly turned into any combination of: Lorne, Sheppard, Ronon, Rodney.
Though I still adored McShep, the fact is they dominated the fandom and I felt some of the other characters, pairings deserved some loving.
Admittedly I’m a Pollyanna once I love a character I stick by them. Separating McShep was easy, but I had rules they still had to be friends, a team while I paired each Rodney with Ronon and Lorne with Sheppard.
For me, why Lorne/Sheppard worked, beside the pretty- because hey pretty, hot! With major drool worthiness
;) Again for me there is no absolute answer, but the SiC aspect is a big part of it. That they know and share a military background, can lean on each other and even if they’re not on a mission together, after the mission they’d see each other – or hell maybe it’s just another height thing (I have a height kink, Sheppard’s taller). So for me, they’re a pairing and it didn’t matter if Sheppard called Lorne: Major, Nick, Marc, or later Evan ♥ - they simply belonged together.
So if you haven't given them a shot, let me suggest perusing the Lorne/Sheppard tags here
Also check out one of my favorite fics, it’s a few years old, but really shouldn’t be missed - its awesome! Tanlines & Dogtags
Btw, my apologies that I didn’t write anything specifically for Lorne/Sheppard (they are one of my fav pairings), but had the flu earlier this month and I’m only now starting to feel better.
