I can see that if you feel like that was supposed to be the series finale. I always felt like that was the set up for the next season that they never did. It does work in a “happily ever after” kinda way though I guess
John Semper (show runner) says it was the finale. He knew what he'd do IF they got picked up again but he already knew the show was cancelled and Marvel was moving on, which is why he broke the fourth wall and had Peter grow up a bit. So yeah that was the ending
