Spoiler: Darth Vader is Luke Skywalker's father. Sorry.
I think there's probably a cut-off point where you have to say look, if you haven't read the book/seen the movie/TV series by now, spoilers aren't spoilers because you left it too late. BK written when? 1879? I think the statute of limitations for spoilers has expired on that one.
Incidentally Marie, that is the best GIF ever. Ev-er.
