Hee! I have *tried* to write Jack/Lorne - I had a follow-up prompt for Jack coming to Lorne post Time Agency to find his path, but I just couldn't make it work and it's such a shame, because you're right. They would be fantastic together!

the Doctor is an ass

Yep. *g* I have finally let go of Doctor/Jack in canon, as I feel that Jack has - but I'm still very, very willing to enjoy it in fanfic! *g*
