Little Witch Academia (2017 series)/Headscratchers

Why is Akko a fan of Chariot?

 * Chariot only used the dream draining spell for one performance, which she just happened to attend. All her other performances are much blander, resulting in booing from the crowd. After seeing Chariot's one performance, Akko must want more, right? She'll attend Chariot's other performances, but they won't be as good as the one she first attends, and god forbid if she attends the one where Chariot performed a Deface of the Moon. One performance should not be enough to make a strong impression on anyone, even if the performance is excellent. It takes multiple strong works to get any creator cemented into a fan's brain; the same should apply with Chariot. We can explain this as away as even the mild spectacles from Chariot's other performances are wonderful occasions to a kid like Akko, but that doesn't explain how the obsession carries all the way to Luna Nova to the point where she seeks out the Lost Words of Arctus solely to meet Chariot. The wonders she felt as a kid must have worn off by the time she reached sixteen.
 * This may be explained away by Akko's personality. Some people can just be wowed by a single performance like that, especially if it's that spectacular. Akko seems like the exact kind of person who would be impressed by a glamorous magical performance. Then she spent so much time thinking about the performance she forgot to attend the other shows?

Exactly who is streaming the video in episode 25?
In the episode, there is a live video feed of Akko and her friends riding on broomsticks to intercept the magic missile broadcast worldwide, but who's taking a video of that? Does Croix send a flying video-robo drone to keep up with the girls? Is it surveillance footage from a very advanced military satellite? The cameraman must be strong, being able to keep up in the sky, flying with witches, and having an exceptionally steady hand.
