Sorta Spoilers Ahead
The shot of Han Solo and Chewie being "home." And my favorite part:
Luke's' voice over talking about the force being strong in his family. While this is going on there's a shot of Vaders' helmet, Luke (?) putting his mechical hand on R2, Leia (?) being handed a lightsaber (YES!) and Luke mentioning it being strong in someone else? I'm guessing the girl in the teasers who has yet to get a last name. Solo or Skywalker? I'm avoiding spoilers so I'm not even trying to remember the first name I saw.
