There was some show....one of the Stargates?....that had a 90 minute episode which obviously couldn't be repeated in the regular one hour slot and yet was part of the series run, so had to be included.
They simply broke it into two parts, and there was a lot of overlap between the two episodes. (A lot of the footage already seen in the latter portion of part one was also aired in the early portion of part two.)
I wouldn't be surprised if they go this route. I mean, it'd really ruin it if they ran a 65min episode cut back to 45 minutes to allow for commercials. (Yeah...in its full form, CAGE is about 65min long.)
The official word, early on, was that they'd do it uncut.
I'm suspecting they'll hold to that, and do it over a two week period.
Hopefully they'll do it early in "season three", as opposed to doing it at the very end, after a year's worth of repeats.
