I think its very likely that we'll learn about the mole in the next-to-last episode as a lead-in to resolve the entire "Light" story line in the finale. I would also suspect that this will result in Robin taking team-lead at the close of the series/season (remember they wrote this knowing it might only go one season) -- they've foreshadowed Robin becoming leader and that would be a strange thing to leave dangling or unresolved.
