“Welcome to Earth, Mister Winchester,” Castiel says, perfectly polite, and Gabriel sees the way Winchester’s antennae twitch with interest when Gabriel spins and pockets his sidearm; a habit of boredom, but Winchester is watching him and Gabriel has made no secret of watching him, either, since Castiel yanked Gabriel back by his jacket with a glare after Gabriel’s suggestion he was going to lunch.
“Nice meeting you, Cas… Gabriel,” the alien says with a warm smile, and by the time he slings his bag over his shoulder, shooting a wink in farewell, Gabriel is smiling back; sometimes the immigrants did notice Gabriel’s fine specimen of a boyfriend and partner, and when the aliens were as hot as Dean Winchester, Gabriel was inclined to let them look (as long as it took for Castiel to sink his hands in Gabriel’s hair and pull him back to attention).
