What an original, engaging story! I was wondering how Harry was ever going to go back to his own universe and readjust to life after experiencing everything on the other side... but turns out he didn't have to! Alternate!Harry will love Ginny and eventually fit into his new life, I'm sure, and it's great knowing that this Harry has chosen to stay beyond the mirror and to continue a life with Snape.
I love Regulus/Remus. As well as Mr. Fuzzems. Actually, I love all the little details and cameos, no matter how brief. Thanks, I enjoyed this very much.
