The first thing they do—no, correction, like the third thing after confirming nobody present owns the dog that's attached itself to Dean and Sam's really intense texting session—is scour the internet for the absolute best noise-canceling headphones in the world. There's cross-referencing, there's passing phones to Jack for accurate translation, there's the ritual sacrifice of credit card information for expedited shipping.
They hightail it back home. (They stop at a pet store on the way.)
It takes weeks to cast all the spells Dean needs for quietude and silence and sleep, to keep them from canceling each other out or combining into something other than what he's after. It's his plan, though, his happiness on the line, and so he's the one who does the work. When he's finished, each spell feeds smoothly into another to form an enchantment so powerful it knocks Jack out cold when he puts the headphones on to test them.
Dean makes one final deal. The Empty accepts, and sinks into the deepest, quietest sleep of its eternal cosmic existence.
("You created one of the most powerful magical artifacts in the entire history of the universe just to get me back?"
"I like to think of it as trading a pair of custom headphones for your life."
And they're both right, but they have time to find the middle ground now.)
