It's not Spidey saving an entire trainload of people from horrible death (who then save him). It's not the civilians (later) standing up to Doc Ock (though both are awesome). Then Peter realizes his mask got lost and has a little moment of panic and the two kids say 'We won't tell nobody'. The others agree.
- Made more awesome by that one guys shocked reaction, realising the sort of person who routinely risks his life to save them.
Passenger: He's... just a kid! No older than my son!
