Jack has made it out of Rapture alive. But he can't quite get one certain Irishman out of his mind, fake or not. Cue Jack ending up decorating his new little house full of Atlas-posters (that he magically acquired from somewhere) and radios, even if he knows he probably shouldn't. He can't help it.

But of course, Fontaine/Atlas has somehow survived as well and is coming to get revenge on Jack for ruining his jam, and he sneaks in Jack's house some night. Interesting things ensue when he finds Jack's Atlas-ridden house.

Bonus points if Fontaine persuades Jack to do the do with him using the Atlas -persona the boy is so very fond of, even if Jack deep inside knows it's motherfucking Fontaine he's fucking.

Or anything remotely like that, please?
