3 things to wonder...
1) Given how he wasn't seen, heard, talked about, etc; I wonder if they are turning Tony Stark into Uncle Ben. Because Peter is acting like how he would do or has done after Ben's death, given him weight on when a student has to become the mentor and doesn't feel like he can, and thus they're applying the MCU onto Spidey's character. I just don't like the "Spidey is the new Iron Man" because Spider-Man SHOULD JUST BE SPIDER-MAN.
but...
2) I also wonder, with this direction and notice on Peter and Tony that in the MCU, Peter will take over Stark's company and take the recent route they did in the comics and have Parker Industries, or something similar.
and...
3) Mysterio creates illusions, correct? What if the multiverse, maybe even the Elementals but that might be pushing it maybe, Mysterio being a hero, everything is all a lie? A lie that has fooled even Nick Fury, but Peter will ultimately find out.
Thats it so far.
