I am a little confused by the way overpowered Reva who we have never heard of before. She seems to have an insane amount of force ability exceeding Kenobi's at this point, which will need to be explained for sure. We certainly need more backstory as to how she got so powerful and why she hates Kenobi so much.

I sure hope they don't do the Rey thing again and make her great at everything without any explanation or any significant training. Mary Sue characters never work as the fans will often reject them based on not being able to identify with a character that is great at everything and never has any struggles.
