"Birth" and "The Bear King" were filmed simultaneously last Season, but that was probably due to the fact that they were given a 23rd episode. I know that they have at also filmed episodes out of sequence before, too. According to Ginnifer Goodwin and Josh Dallas, "We Are Both" was actually filmed before "Broken", due to some logistical reasons. I'm not so sure that's happen with 604 and 605, but I guess it's not impossible.
