Everytime I see that scene in the trailer, I think it's actually running backwards... I think Luke is handing the hilt to her, not the other way around. Maybe it's just my eyes but it's the way the hilt is coming out of her hands seems like the clip is running backwards for some reason. I know Lucas loved doing that with SW films. Look at ANH when the tusken raider is standing over Luke with his his waving it in the air and pumping it up and down... it's actually the same small clip running forward and backward a few times with the sound effect added later.
