   Summary

   Regulus Black has been falling into alternate universes since he was seventeen.

   At this point, he knows the routine.

   Wake up. Check the ceiling. Find a mirror. Figure out how old he is. Locate Sirius. Locate James Potter. Discover whether James is his boyfriend, husband, ex-boyfriend, future boyfriend, or simply taking an offensively long time to fall in love with him.

   Easy.

   Except this universe appears to have made several catastrophic errors.
