Here is what happened in the other world.
Bellatrix, not Severus heard the prophecy and decided, after telling voldemort, to take matters into her own hands. She attacks Lily, before Dumbledore gets the chance to explain the prophecy to James. Lily is tortured, but Snape, who like in the other universe is still in love with Lily, overheard Bellatrix and Voldemort and came to the rescue, stupifying Bellatrix. Bellatrix, under veritaserum tells that Pettigrew is the one who tipped them off to the Potter's pregnancy and their location.
I hope that clears things up. I have gone back and forth with this chapter so many times, trying to see if things made sense, if they were all jumbled. Then I came to the conclusion, that I am writing because I enjoy it, and I want to get my ideas down. Maybe it doesn't make sense to others, but I have read plenty of fics where things do not make sense. Mine can't be the worse, at the same time it can't be the best, but I'm satisfied because I love writing. :) Hopefully some people will still find enjoyment in the story. If you have suggestions, I'll be happy to hear them. I may at one time come back and rewrite this part. I knew the outcome, but now to get there. So now on to the responses to reviews:
SeparatriX: It is a big mess up. Sirius should have realized, but then again he might not have know how exactly the pendant worked, or that it could make such a thing possible. But in any case, yes Sirius should have made himself more clear with his directions. :)
bledding black rose: Glad you found it interesting! Hopefully your questions are answered with this chapter. Sirius and Remus didnt recognize Harry, because in their world he doesn't exist.
adge9631: Yes, Harry is in another universe. Sorry this update took so long. I could not get my head wrapped around this chapter, although I knew what I wanted to write, it would not get written.
Kenaz Slytherin: I am glad you like it!
Ca'n Stella: I certainly hope so! I'm a bit out of practice with writing, so I'm hoping I can keep it interesting and make it make sense.
ChristinaAngel: Sorry for the delay in update! hope you continue to enjoy!
Bewitched Hybrid: It is not a time travel fic, it's a universe hopping fic, as I call them. I have tried to tweak certain events to make the current situations plausible. Hopefully I somewhat succeeded. :)
rekahneko: Here you are! As for harry growing up there, you'll have to wait and see ;)
