When all the jedi voices came through in the final scene, I thought maybe we would see Anakin, Obi-Wan, and the others, but for some reason they limited them to just voices.
Since I was watching a German dub, it literally meant nothing to me since I couldn't possibly recognize who was talking.
We got a lot of hints that Finn is force-sensitive, but that never went anywhere. They didn't even finish the plotline where he wanted to tell Rey something before they died.
Some think that he wanted to tell her that he's force sensitive, but to be honest, it seems like a really weird time to bring that up if they think they're about to die.
