Mess up

This Spider-Man is young, inexperienced and totally unfamiliar with an environment involving other super-powered individuals, so throwing him in with the Avengers is bound to result in some mistakes – and that’s something we’d actually like to see.
It would be unrealistic to expect him to put in a flawless performance against so many seasoned heroes, and messing up – even if it’s in a big way – will help the character develop in future movies.
We don’t necessarily want him to make a mistake that ends up with someone dying – that’s not going to be good for the character at all – but have him experience what it’s like to make an error for the good of his character. He might even make a joke out of it.
