Sheppard sips his coffee as his attention wanders back to McKay. McKay's not conventionally good looking - he's balding, he's got a little belly and his mouth does that weird drooping thing.
Sheppard puts his coffee down and sighs; McKay's also got beautiful eyes, a great ass and wonderfully broad shoulders. And besides all that - he's funny, sarcastic, cutting, frighteningly intelligent and has the most amazing sense of humour.
Sure, he hasn't fallen in love with McKay or anything, but, he admits to himself with a wry grimace, he's only holding on by his fingertips and the edge is crumbling fast.
