They're doing it on purpose, Owen thinks as he watches them over the edge of his glass.
Bumping noses and small smiles and forgetting that there's anyone else in the pub. Slow kisses and Ianto resting his cheek against Jack's shoulder, hand on the other, curling his fingers into the dark material of the Captain's shirt as his eyes slide shut. Whispering into Jack's ear, his eyes still closed, both laughing quietly and for one moment Owen swears he can feel the hot breath ghosting across his own cheek, the quiet voice softly telling him...
When did Ianto start licking his lips every five seconds, anyway? When did that laugh start becoming so loud and clear to him, making his stomach flip? He's gone mad, he thinks, mentally blaming the Rift and whatever alien object it sent through to cause this.
Then he notices Jack staring at him over the table, dark eyes looking out from behind the brown hair that's fallen down. He holds Owen's gaze for a few more moments, smirking, with his arm possessively around the younger man, before he turns and leans back to look Ianto in the eyes.
"Mine," he says, only just loud enough for Owen to hear, and pulls Ianto forward for a kiss, twisting the blue tie around his hand. Owen lets his own hand slide down the outside of his drink, wondering how similar the glass and dark silk feel.
Owen closes his eyes, shakes his head, and turns to look at Gwen. Fucking tea boy.
