New SuperWood headcanon: Jack reads human!Cas to sleep.
Cas has a number of troubles that converge to keep him awake. Drugs help, but everyone in Torchwood – by experience now – acknowledges that Castiel and heavy meds are a bad mix.
One night, feeling hollow and wrecked from weeks of sporadic insomnia, Castiel slumped on the office couch. Nearby, Jack read off an article about a new piece of Chinese space exploration equipment. Something about the Mandarin, the cadence, Jack’s voice, or the soft constant sound against the silent Hub, Castiel didn’t know. But he woke up fifteen minutes later at Jack’s gentle nudging.
“Come on, Castiel. You’re gonna wake up with knots the size of terriers, you sleep here.”
Not long after, Castiel was cocooned in blankets and propped against Jack’s chest. Jack – on a whim – asked to read Castiel the rest of the article.
It worked.
They’ve worked their way through shelves of books, in a number of languages. This month it’s a Russian text on Siberian Faeries from the Men of Letters catalog – sent special delivery by the Winchesters.
A note from Sam tucked inside slyly hints that thickening Jack’s pronunciations might work to his advantage, later.
