This scene of the teaser trailer looks interesting.

And I noticed something that is both surprising, and cool in this scene.

A person wearing armor that resembles the armor worn by Clone troopers comes out of the cloud of dust. If you watch this part of the trailer, you can see that this figure and a second figure are wearing jet packs similar to the ones worn by Jango Fett and Bobba Fett.

I wonder if this new character, Zorii is from this location.
Then we see Poe, Finn, and C-3PO in some kind of pod or vessel.

Someone is shooting at them, and they are obviously shooting back. I wonder if the two people with the jet backs are helping them, or if they are the ones who are shooting at them.
C-3PO looks so funny in this scene and if I know C-3PO, this scene is going to be hilarious.
Then there was a scene that was pretty brief, and I didn't even notice it the first time I saw the trailer. But I watched it a bunch of times and I noticed this:

It was a very brief scene right after the one with Poe, Finn, and C-3PO, but it's not part of the same scene.
It is hard to see in this scene, but I never remember seeing a ship that looks like this in a Star Wars movie.
Whatever kind of ship it was, it almost appeared to crash into what appeared to be a star destroyer. It was really hard to tell because the scene was so brief.

Then this scene appeared...

After I watched the trailer I was trying to figure out what this was.
Then I was showing the trailer with one of my best friends Winter Wolf, who is literally the biggest Star Wars Fan I have ever met. They are also the Star Wars expert of everyone I know, they have like three different Star Wars encyclopedias and other Star Wars reference books. Winter Wolf reads all of my Star Wars theories before I publish them to make sure I am not making any huge mistakes about Star Wars.
(And she does Winter Wolf just stole her phone for real hi Star Wars Fans✌️)
When Winter Wolf saw this scene in the trailer, they became very excited.
Me: "what is it?"
Winter Wolf: "It's one of the medals that Leia gave Luke Skywalker and Han Solo at the end of A New Hope after they blew up the Death Star!"
Me, feeling ridiculous for not realizing that sooner: 😮 🤦‍♀️
So this is probably Leia holding most likely Han's medal, but possibly Luke's. Even though it might not actually be Carrie Fisher, since we only see the person's hands, and they had to use deleted footage.

Now we get to the part where I actually started tearing up...

I started crying because I know that Carry Fisher is no longer with us, and the first time we get to see her as Leia in Episode IX after she is gone is this touching scene.
I was a little surprised that they were willing to show this scene before Episode IX came out, I was expecting them to try to surprise as many people they could with her role in Episode IX. Even after the fans found out that she was going to be in Episode IX, most thought that her role would be very brief, and that she wouldn't really come in contact with any of the other characters. Or that she might actually be in the beginning of the film and then die a few minutes into the movie.
But this scene gives the fans what Leia's character has always been to the Star Wars fandom: hope. This scene is far more real and deep then what I thought they would be able to get out of the deleted footage. But this is the kind of thing I really wanted to see from her character in Episode IX. She is the last living character of the original trio and because this will be Carry Fisher's last movie I didn't want her role to be distant, I wanted her role to be close and sentimental. I wanted her to be a leader, but also a mother figure to all of the new characters. I am glad to see that there will be at least one such scene.
My father and I were actually discussing her role in Episode IX. I told him about the unused footage. He suggested that she could be on another ship throughout most of the movie and only appear to the other characters as a hologram delivering messages and orders. (Which was a pretty good idea) But then at some point, the ship that she is on gets attacked and blows up so that they wouldn't have to show her death scene. (Which I kind of felt like wasn't the best end for her character, but it wasn't as bad as some fanfics I've read.)
Then I suggested that she could become a Force ghost, because it would be easy to use any footage of her for that purpose, perhaps even make her young and use some unused footage from the originals that they might be hiding.
But this is far better than I had hoped. And if you have read any of my Episode IX stories or fanfics, you've probably noticed that I like to give her a pretty big role in them. Mostly because I want her to get to see her son redeemed.
Which brings me to the next reason why I am so happy about this scene. If they were actually able to do a scene of Rey and Leia together, we might even get to see Leia and Ben together. She might actually get to see her son come home, I hope!
Another scene I would really like to see is Luke's Force ghost with Leia.
Then we see Rey.

Then I noticed the tears on her face. And I had tears on my face, thinking about Carry Fisher.
Me: "I know how you feel, Rey."
Me: "wait, why is she crying!?!"
So these are all of the possibilities I could think of:
1. Maybe they were talking about Luke, Han, Ben or all three
2. Maybe someone died, which could be anyone besides Rey or Leia. (But because Rey is crying and Leia isn't I don't think it's Ben, the same would be true if it was Chewbacca or Lando, and even Poe since he is like a son to her. I don't want to scare anyone but there is a possibility that it's Finn. I really hope that it's not, but he's the only one I can think of who's death would make Rey cry, but not Leia, since she doesn't really know him that well.
3. Maybe Rey had some kind of vision in the Force and she is telling Leia about it
4. Maybe Rey is just thinking about how her parents abandoned her
5. Maybe Ben was redeemed and Rey is crying because she's relieved (Winter Wolf stole the phone again that's not a relieved smile her lip is shaking)
6. Maybe Leia has become like the mother she has always wanted.
7. Maybe Leia is about to sacrifice herself for the Resistance (it would explain why Rey is crying and she isn't)
8. Maybe Rey tried to bring Ben back and couldn't, and she is crying because she failed. And Leia is comforting her because she knows that Rey did everything she could and she also feels responsible.
9. Maybe Rey had to stay on this planet alone for a while or got trapped there somehow but Leia came back to get her, unlike her parents and she feels like that would has finally begun to heal because someone she looks up to like a mother came back for her
10. Maybe Rey was just in a fight with Kylo Ren and Leia told her about how Luke saved Darth Vader, and she realizes that she has to do the same thing for Ben
Please comment and let me know what you think of all of these, or if you have any ideas that I have missed.
Then we come to this scene:

Which looks really epic, and reminds me of Middle Earth. (Sorry of topic)
So in this scene, we see Rey, Finn, Poe, BB-8, Chewbacca, C-3PO and the other droid.
They are all standing there looking off into the distance majestically, like the company of Thorin Oakenshield in An Unexpected Journey. (Sorry I did it again.)
Then the scene pans over and we get to see what they're looking at.

Me watching the trailer:

It has to be one of the Death Stars!
Look at the comparison:
