I was slightly disappointed it was Qimir as well, but it was so obvious at the end of episode 4 that I was over it. However, I assume the fact that this reveal came in episode 5 (and the fact that the show is called the acolyte and that Qimir specifically said he was looking for an acolyte) means that Qimir has his own master out there somewhere. That could still be interesting.
But then someone pointed out to me yesterday that the most likely master would be Mae’s mom and that seemed not exciting once again.
As an aside, I don’t think they have any canon issues with the line from TPM unless they are incredibly stupid. People could all die, it could be ignorance, it could be a cover up. I don’t think that’s a big issue.
