Place To Call Your Home (слэш)

Being thrown back in time one hundred and fifty years? Not the weirdest thing to happen to Tony. Going so far back he needs a message from future-Thor and the help of Asgard to try and get him back? Still weird, but really useful.
Only, despite meeting the never-before-heard-of talented and magical brother Loki, it doesn't look like he'll be getting back in a hurry. This wouldn't be a problem except, he not only has a life and a girlfriend back in the future, but he and Loki are getting along better than anyone he's ever met. They're connecting in ways that are dangerous.
And, if those weren't big enough problems, there is also the ever present worry: what if I can't get back home?
