I feel like people are jumping to conclusions that are just the trailer messing with us. The first is that Luke is scared and is going to be a whiny baby the whole movie. I can almost assure you that will not happen and if it does there's a serious problem lol. I'm sure Luke will have good reason for how we've seen him act so far and he will come around in the movie. Another one is that Rey is going to join Kylo on the dark side. I really think that was just the trailer being cleverly cut together. Third is that Kylo will kill Leia. Is it possible? Sure, she's going to die at some point but I'm 99% sure it's not going to happen the way the trailer tried to make it look. A lot of people are forgetting that we know almost nothing about Snoke and what happened with Luke since we last saw him. There's going to be a lot that gets cleared up in this movie and I think anyone that thinks they have it all figured out from the trailers is mistaken.
