getithere | B/J time travel story

A long time ago I read this story, but forgot to bookmark it : \ . I think this story starts off when Brian goes away for business, and he leaves Justin in the loft telling him to forget their trip to Vermont. In the trip something happens, and Brian gets drunk and comes across a mirror. While he's starring at himself, he switches places with the Brian from another universe in which Justin actually died at his prom. In this university, Brian never met Justin, he actually answered his cell phone and ended up at the hospital with Lindsay. The story revolves around how both Brians deal with how their lives could have turned out. I know that Justin and Michael end up siding together to try and figure out how to fix things, and in the ends it's Mysterious Marilin (who I thing is a guy in the other universe) who helps both Brians return to their respective lives. I think there's something about wall monsters or some such thing that are supposed to guard the "doors" and one of them messed up, hence the switch.

Anyways, if anyone remembers this fic, could you please provide a link??

Thanks,
