"He should have worn the RAF uniform," Jack complained, leaning back in his chair.
"His position in the Irish Guards is of a higher rank," Ianto said calmly, again.
"He is serving in the Royal Air Force."

"--serves in the RAF search and rescue, not the Irish Home Guard. That title is only honorary, he should be wearing the blues, he--."
"It's politics, Jack. And he is wearing his wings. Hush."
Jack grumbled under his breath, but Gwen and Ianto ignored him, leaning forward to watch the vows.
