If you want to be very safe, once you start seeing numbered TV Spots, it’s time to go. If you’ve been combing all of the promo material like some of us have, then you might accidentally start putting stuff together that wasn’t meant to be directly spoiled. However, if you do feel like you were unintentionally spoiled, don’t worry! It’s easy to jump to conclusions when you’ve only got part of the puzzle. Before Civil War, I assumed this shot:
correlated with this scene:
because we hadn’t any hint of Vision’s mistake in any of the promo and I figured they were probably going to keep (Jonas) Vision’s big moment from Civil War.
So, even if it seems like you find something out, there’s still a lot of misdirection and misinterpretation going on, and you might be less spoiled than you think.
