The assistant director had been watching the audience's reaction. This year, they were experimenting with livestreaming their filming process, then editing the footage into a full-fledged episode.
This way, they could drum up lots of hype for the episode itself as well as determine which parts were the most popular with the audience so that they could maximize the effect when editing the footage.
After having used this method for the past three episodes, they'd found that it was indeed quite feasible. Not only that, because they couldn't show everyone's point of view at once on a livestream, they could edit in some scenes that were previously unseen by the audience, which would help stir up even more anticipation.
