User blog comment:SibunaSeason34/House of Anubis - The Touchstone of Ra: Changed Script?/@comment-4741712-20150211180755

About the plot change: I can think of two reasons why they changed it: 1. The ending where KT turns to stone was filmed, screened to a test audience/focus group who responded negatively to KT turning to stone, and this made the producers decide to re-write the ending where KT lives and re-film it. Endings are what typically change when testing a movie, and I'm probably the minority when I say this: Had the original ending with KT turning to stone be kept in tact, I wouldn't have liked it as much. It's too sad an ending for me to be satisfied with it (as much as a cop-out of "The Osirian may be dead, but the boy lives" is). 2. Another possiblitiy is that they re-wrote it once they realized Season 3 wasn't fairing well. This doesn't mean that they knew HOA was going to be cancelled/on hiatus/not renewed yet. But I'm sure they weren't stupid. If HOA was to return for a season 4 for sure, they might have kept the original ending, but with the uncertainlty due to Season 3's low ratings, they probably wanted to change it. KT living and Sophia turning to stone, with the Osirian losing his powers but living would be a more satisfying ending should HOA not return again. TBH, I would have thought had Nina been a part of Season 3, I would have assumed that Nina as the Chosen One would have taken Eddie's place in the ending, with a reunion with Sarah Frobisher-Smythe explaining the "powerless Chosen One" thing, similar to the end of HHA. I believe Studio 100, Lime Pictures, and Nickelodeon where already discussing Season 3 plans long before Nathalia Ramos said she wouldn't return for Season 3. Those are my theories about it. I'd probably go for the second theory as to why they changed the script so that KT lived simply due to the fact that the video only shows KT turning to stone on a 3D animated stage as a mere demo as opposed to any actual footage emerging. Just thought I'd share these ideas!
