I mentioned this in a comment on the Season 4 page, but thought I'd start a formal discussion about it.

The reason that ABC formally announced that they'd given Once Season 4 an additional episode is to account for the second hour of "Smash the Mirror", which will, when all is said and done, constitute an episode all on its own, just as happened with episodes such as Star Trek Voyager's "Dark Frontier" and "Flesh and Blood" (which are considered to be episodes 5x15 [Dark Frontier, Part 1], 5x16 [Dark Frontier, Part 2], 7x09 [Flesh and Blood, Part 1], and 7x10 [Flesh and Blood, Part 2]. This means that, by the time all is said and done, each episode beginning with "Fall" will have its order number shifted up one.
