Do the Special Features Have Any part 2 spoilers?

I'm looking forward to getting the Blu-ray release of Wicked, but before I watch the extras and listen to the commentary tracks (which I think are the same as in the digital versions?) I just wanted to check if anyone's watched all of them, and if there were any spoilers at all for Part 2? (As I'm doing my best to avoid them...even if I've already failed to some extent 😭)
