Lan isn't here.

( he hadn't been in moiraine's initial time here, though apparently in that unknown period between her disappearance and return he had been here. had nynaeve's time crossed with that or were they both unlucky? )

It would seem that what returned me returned him also.

( and moiraine says that confidently, knowing that he wouldn't have just ridden off somewhere -- lan didn't just leave )

If you hope for that to reverse it can't be counted on.
