Last Chapter! A short one I know, but a nice round off I hope.

After having finally removed the bullet, Jack rested for the night and was fully healed the next day except for some scarring which would be gone in a few days. Castiel had been his usual strict and protective self, keeping Jack's activities to a minimum and being on constant surveillance, just in case anything happened again. By now a week had passed and Jack was still as fine as the morning he had woken up, he had managed to convince his 'bodyguard', after many final checks, to take a break. Cas had agreed and went out with the Winchesters for a couple of hours, leaving Jack fully alone for the first time in a while; he was nervous, but knew in his heart that his Captain would be fine. All the time he was absent he was worrying, but managed to refrain from calling.

When they arrived back at the bunker, the angel hurried in to find his patient. As he scampered down the stairs he called out for him, "Jack," starting off calm, but when no response was heard he cried louder with more desperation, "Jack!... Jack?" As he rushed in and out of rooms, calling in every doorway, "JACK!", searching in fear of what he might find, hoping to God that everything was alright.

"JA-" He stopped in his tracks as his eyes locked onto Jack's feet sticking out from behind a table. He ran over preparing for the worst, but when he turned the corner he skidded to a halt, his heart skipped a beat or two as he held his breath in shock, feeling both relief and anger.

There in front of him was the immortal, absolutely fine with the biggest, smuggest toothy grin pulled across his handsome face, crouched down with his hands extended out in front of him. Raising an eyebrow, Cas pulled his adorable confused face as he didn't immediately grasp this human action.

Jack couldn't quite tell whether he was legitimately lost or playfully acting naive to get revenge after being tricked, but he rolled his eyes at him, "you really do know how to ruin a moment don't you," he laughed a little and straightened himself up again.

He coughed, clearing his throat and seemingly bringing a new seriousness to the air, he peered up at his angel who equally peered down at him. Then as they stared deeply into each other's eyes, sharing a bond that only people cursed with immortality could share.

He said in a low soothing tone "... I'm down on one knee Cas," he opened the small box in his hands to reveal a shiny silver ring, "will you do the honour of making me the happiest man on Earth? Spending the rest of eternity with me? And loving me for the rest of time?... Cas..." Harkness glanced down, the angel noticed him fiddling with the box nervously, which was an unusual behaviour for him; it came across as sincerity and devotion, as for once something wasn't a joke.

Jack, still waiting for some sort of reaction, continued with his speech hoping Cas had got the message, "will you m-"

Just as he looked back up to reconnect with those gorgeous deep blue eyes mid question to plead for an answer, he was stopped by the soft gentle lips of an angel planted on his own. Then Castiel put his hands on his cheeks and pulled away, staring deeply into his soul with his ancient eyes, "of course I will Jack," the corners of his mouth pulled to create a small innocent smile. Jack took Cas's left hand and brought it up to eye level where he carefully slid the ring onto his finger.

The angel furrowed his brow again in puzzlement, "when did you...? How did...?" clearly forgetting about the immortal's ability to travel through time and space with his vortex manipulator.

Jack chuckled and tapped his wrist, "I visited an old friend. Popped out for less than a second while you were gone. Best jewellers in the galaxy."

Castiel held his hand up to examine the ring just like he'd seen women do in the movies after a proposal, he gave it a try out of curiosity as to why they did it. It caught the light and a rush of warmth ran through him, "it's beautiful," he said, seemingly losing control over his own thoughts.

"You know what else?" Harkness began, feeling so pleased and finding it hard to hide his excitement, "can you tell what it's made of?" The ringed hand was brought closer to the angel's scrunched up face and narrowed beady eyes as he analysed the metal. But Jack couldn't control himself, "I held on tight to that bullet Cas."

"The last Colt bullet," the angel replied, looking up and meeting his eyes again, expressing his affection.

Then Jack took his hands, "and now it's yours to hold onto and watch over forever and ever."

That's it! That's the end. I hope you enjoyed it and thought it was a satisfactory ending. Thanks :D
