well, you're off to a rousing start and I love how the temporal transplant did more than just bring Neville back, it altered who was the BWL. With his "memories" of the future, though, Neville should be able to befriend Harry earlier and help him along the way. The two of them should make quite a team, esp. when their ladies join with them. Methinks Ron is not going to enjoy this too much, though, as his jealousy won't allow him to just share Harry's friendship instead of nearly monopolizing it as he does in canon.

True; Ron just isn't as motivated as Harry and Hermione are; and will be relegated to the sidelines most of the time.
