Help finding a Jack/Ennis + Jack/OC fic

[piyo_chiko]

Could anybody help me? All I remember about this fic was a scene where Jack is in a bar meeting another guy. He tells the guy about Ennis and the man responds, "Why'd his folks leave the 'D' off his name?" and Jack laughs.

If anyone can recall which fic this is and where it is, I'd be forever grateful!
