To me that seems kind of like bullshit and I've never really bought that Luke started to go down the path of the Dark Side at that moment. He lost it briefly but after he realized what he did after chopping off Vader's hand he realized what was happening and stopped so to me he seemed in control. If that's honestly used as an excuse for him to turn in the new film and become the villain that will be incredibly lame if you ask me. I think Abrams knows that people don't want to see that too and would be pretty stupid to follow that kind of a storyline in my opinion. If anything I agree with what Ranger said in that maybe him being in isolation for years is due to the fact that he was worried about possibly turning and he wanted to be away to protect those that he cared about. Maybe show him struggling a bit but don't fully turn him.

She's on a secret mission and appears to be working for Leia. She is killed during an attack on "Rose's Pub" and her death brings Leia and Threepio to the planet where they have an awkward meeting with Han.

After escaping the brig, Poe appears to part ways with Finn and Rey. I'm guessing he flys his X-Wing back to the rebel base. Finn and Rey find the Falcon docked on the desert planet and steal it to escape the Empire. This is probably the scene from the trailer, which explains why it's being flown poorly. Once in space, the Falcon is "swallowed" by a giant freighter ship. Han is on the freighter and tells the kids to get out.

A gang of some kind contact Han on a video screen. Han informs them about the cargo he's carrying (which is described as creatures of some sort). Han hides Finn and Rey, but they end up pulling a fuse to create a diversion. The living cargo is released and drag Finn away, but Rey manages to rescue him. A big fight ensues with Rey fending off the gang single-handed, though Chewie is injured. They all race off in the Falcon, splattering the "cargo" against the cockpit window in the process.

The crew later meet up with "Rose" (a codename for the little blue alien that is rumored to be Lupita's character). This creature runs a pub on an exotic planet. It's here that she takes the group to a hidden chamber under her establishment and shows them the flashback of Luke finding dead Padawans at an academy. Rey and Kylo Ren are mentioned as being in this flashback, which strongly implies they were once studying under Luke. That would explain how this young girl can handle herself against an entire gang.

I suppose Rey could have been hiding on the desert planet if Kylo is killing all of Luke's students -- and the fact that Han just happened to be close by makes me strongly suspect she's his daughter after all. I'm also guessing this "Rose" character worked with Luke at the academy. Last year, MSW described a piece of concept art featuring one of these aliens instructing a group of students.

The report mentions "Rose" presents the saber to the group and we learn in the flashback that she smuggled it away during a raid (CLAN vs. The Seven, whatever that means). This bit kind of invalidates the "lightsaber floating in space" rumor we've heard previously. Anyway, Finn is fascinated by the weapon, but Rey storms off in disgust. The pub is then destroyed using the Empire's new weapon -- which is how "The Emissary" meets her end. It sounds like she's could be an agent who acts as Leia's eyes and ears in the field. Perhaps she was assigned to keep tabs on Rey from a distance if she really is Leia's daughter? Or maybe she's just spying on Han? Whatever the case, Leia and Threepio seem to come into the picture at this point.

EDIT: More info about Leia's role in the movie -- as well as the super weapons possessed by both sides:
