This is all stitchlock’s fault. I wrote Martin Crieff/Jack Harkness:

Flyboy – When Martin Crieff gets a ride from Jack Harkness, he gets more than he bargained for.

teaser below the cut

Jack grinned at the young man looking for a ride from the airport. A captain, by the looks of things, and maybe he’d had a rough day. Jack sauntered up to him. “Hello there, Captain.”

The young captain turned and blushed as he looked him over. “Er, hello.”

“Captain Jack Harkness, and who are you?” Jack gave one of his warmer grins, enjoying the way the man blushed harder. Gingers were fantastic for that.

“Captain Martin Crieff,” he shifted his bag. “You fly?”

“Oh I’ve been around the world a few times,” Jack winked. “Need a ride?”

Martin stammered and somehow got out a nod. Jack put a hand on his back and guided him to his car. Jack chatted easily as Martin gave him directions. They finally pulled up to his place. “Well this is my attic, have a good evening,” Martin started to get out.

Jack put a hand on his arm. “Sure you don’t want to invite me in?”

Martin stared at him a moment. “Would…you like to come up?”

I also share that headcanon about jack and nine

kamala-reyes:

That Jack was in love with Nine? Yeah, it’s my favorite one and I think it should have been something touched upon if stated by the show. Honestly the only thing that would have gotten me to watch Eleven again would have been Jack’s reaction to seeing him once again in that new body. Would have been interesting.

It is in my opinion that Nine, stole both Rose and Jack’s hearts. Then Ten came and his relationship with Rose fully bloomed as Jack was left as a comrade, a friend he loves but not in love with. Hm, maybe it’s better that Eleven and Jack didn’t meet, something tells me that Elven would have broken Jack in an irreparable way. Plus Moffat, I don’t trust Moffat with jack-shit much less actual Jack. 

As it stands I want him and 12 to meet, because Capaldi and I sense Moffat is going to go away; i can feel it in me’h bones!

#seriously though#Eleven would have broken jack much a like a child would have broken a toy#and then just looked at him and then demand why did Jack broke himself#when he knows perfectly well he’s responsible for it#I have trusts issues with Eleven ok
