Ok I realized last night as I was going to sleep that Trap is ACTUALLY secretly part of the Unbreakable universe, and it was most definitely not made as a one and done, I think there will be a sequel and it will bring in callbacks from the other movies. Bruce Willis is too sick to act anymore so unless they shot stuff ahead of time (they may have) we probably won't see him, but it's still cool that it's a continuation of a world, done so subtlety I didn't even notice it at first.
