Okay, so I've read the reviews and so far everyone seems a bit confused...
So far, the two stories are unrelated, but they do end up meeting, and Al, James (and Lily as well) end up time travelling.
The reason I used the pensieve was because I didn't want it to be too cliched, with them breaking a time-turner and travelling backwards. Read the next two chapters when I update it, and it will all make sense and fit into place, I promise
Thank you so much for reading and to those who reviewed - I'd love to hear what you have to say!
(chapter three is marauders, chapter four is future gen, and the meet in chapter five)
