Jack never slept. At least, that's what Ianto thought. Jack was always awake when Ianto fell asleep, always awake when he awoke. Ianto had just assumed Jack never slept, due to horrid memories he'd buried that only came up again in his sleep.
But Ianto was wrong.
Once, only once.
Ianto Jones woke, rubbing his sleepy blue eyes.
Due from the lack of light filtering through the blinds and into the room, it was early morning.
Ianto'd shifted his position and glanced over at Jack Harkness, thinking he'd be waiting for the younger man with the vibrant I-just-drank-eight-cups-of-coffee look in his eyes.
Instead, the older man was snoring quietly beside Ianto, his arms and legs flung about the bed, his hair disheveled.
Ianto sighed and sat up carefully, trying not to make the bed springs squeak. A single spring squeak loudly, and Ianto winced. Jack didn't stop snoring, his eyelids didn't even flinch. Ianto let out a sigh of relief.
He wasn't sure why, but it seemed something like a crime to disturb something so…natural, beautiful, even.
Ianto reached out a tentative had to brush back Jack's light brown hair. It was soft and damp with drying sweat. Ianto froze up when there was a hitch in Jack's breathing, but it soon became steady again.
Ianto smiled and let himself notice things about the Captain he didn't have time to notice in the day. The curve of his throat, the shape of his lips, the broadness of his forehead.
Ianto grinned as Jack drooled a little in his sleep.
Turns out, Jack did sleep.
