Due South/Man From U.N.C.L.E. (G)

Title: The Man in the Window Seat by Shay Sheridan (G)
Pairing: Fraser/Kowalski
Author on LJ: shayheyred
Author Website: Chez Shay
Why this must be read: Do you recall the famous words of John Greenleaf Whittier: “For all sad words of tongue and pen, The saddest are these, 'It might have been'.”? Ray doesn't. He boards a plane back to Chicago, leaving Fraser in Canada without ever speaking of his feelings. On the plane, he meets an older, wiser man who still asks himself 'What might have been'. Will he convince Ray not to make the same mistakes he made?
 

Excerpt:

"Of course, Ray. And I'll miss you, too." But Fraser wasn't meeting his eyes, and after a moment Ray decided not to go in for the clinch like he'd told himself a thousand times he would. Coward! But he couldn't make himself move, couldn't make himself do it. Because he was wrong, he'd read Fraser wrong, he didn’t feel the same way. The look on Fraser's face told him that. It was plain to see that Fraser'd had enough of him after three months of being together day and night. Christ, the guy probably couldn't wait to get back up north to his cabin, go back to being a Mountie, all by himself, without the encumbrance of Ray Kowalski weighing him down like an anchor slung around his neck.

There's also a lovely remix from Fraser's POV: Of All the Wonders (Appassionato Overdub).
