Summary
It’s not normal to feel this way about someone. Shiro knows that, and, logically, he understands that Keith is a big boy who can make his own choices, but this is a young man Shiro watched grow up, who he grew with, side-by-side, who he mentored and looked after. There’s no question in Shiro’s mind that he’s sick in the head, that Keith deserves better than him, that he deserves someone as unblemished and untouched, as perfect, but Keith wants Shiro, and Shiro is too selfish to say no.

Summary
Shiro wakes blindfolded, bleary, and tied to Keith.
He can't recall most of what's happened leading up to their capture, but what he does know is this: he's having issues, newfound and pressing, from being bound so tightly to his best friend, and those issues are the kind unwise to dwell upon in their current close-quarter situation. He and Keith need to devise a way out of here, and fast.
But Keith, oddly quiet above him, seems to be having issues all his own.

A cheap motel, Sam snoring in the other bed, and Castiel sitting silent by the window. Dean tells himself he can be quiet, tells himself he won’t get caught. But Cas always notices. What follows is wordless, raw, and unforgettable, something they’ll both pretend never happened come morning.

Summary
Maybe Keith’s words have loosened his betrothed’s fierce grip on tradition and curtsey, because he looks up and their eyes meet.
And oh.
Keith swears the gravity beneath him shifts. It’s like everything his mother said when describing the tick she met Pop — how the whole world shifts on its axis and the planets change their orbit and how he just knows that this man before him is the one.
In which a political betrothal to the Altean Admiral becomes so much more than Keith anticipated.

Summary
Next to him, Keith is studying an electronic flip board with the same intensity he employs during intergalactic summit meetings. DEPARTURES, it says. “...Yeah. It looks like our flight is still on time.” He hikes his bag up on his shoulder and whispers their gate number under his breath. He’s been reminding himself of it since they retrieved their digital boarding passes the night prior. “C’mon.”

Post canon, on Earth, Shiro takes a flight with Keith.
