Do Not read if you haven't   watched the movie there are some spoilers 

If you have seen the star wars trailer you would hear emperor palpatine saying to Rey, ̈ long have I waited ̈ and then it goes to another screen, but in the movie emperor palpatine says, ̈ long have I waited… for my grandchild to come home ̈  this shows that Rey is a palpatine and Rey's mom or dad was palpatine ́s kid.

Here's the very last trailer for Star Wars: The Rise of Skywalker ...

Rey got a cool new lightsaber kyber crystal and the color is yellow. She also wants to forget her true identity which was kinda the theme of that movie finding your identity and she chose the one she wanted which was Rey Skywalker.  

Another key thing at the climax of the movie is when Rey is calling to the Jedi in the force repeating “Be With Me” you can hear voices of Ashoka Tano, Anikain Skywalker, Luke Skywalker and Obi-Wan and a few others. At this moment Rey is seeing the destruction of her friends so she stands up against her Grandfather and he shoots his force lightning at her while she blocks with Luke’s lightsaber and Palpatine says “I am all The Sith!” Then Rey uses the force to grab Leia’s lightsaber and then says “I am all the Jedi!” Then she repels the lightning into Palpatine’s face and then he dies.

One thing that we saw was that the finale was kinda like Avengers: Endgame. When Lando brought in all those people in the ships it was like the portal scene, and when Palpatine said “I am all the Sith”! He was like Thanos saying “I am inevitable!” And that’s the same with Rey and Iron Man.

One thing we liked was the comedy in the movie and the new characters. One new character who was very likeable and cool was Zorii Bliss which was a character that had a background with Poe as a spice runner which i”ll just say in the real world is illegal and the greatest back and forth comedy line conversation was in this movie. Finn says “You were a spice runner?” Then Poe says “you were a stormtrooper”!? Then Rey says “Were you a spice runner?” Then Poe responds with “Were you a scavenger?!” “We can do this all day!”
