I think we’re talking about two different things. The point of OP’s post was the Director sharing thoughts about this being the origin story conclusion for MCU Spiderman. That’s not something we saw in the movie itself. Yep… we saw the part where no one knows who Peter is. We didn’t see the part where the Director talked about what it means in general for MCU spiderman.
Just read it, and now I am wishing there was a full length novel. Such an intriguing premise! Going to pick up the author’s 3 novel arc starting with Emissaries from the Dead. Author’s name is Adam-Troy Castro.
