Homecoming and the new Marvel Holy Trinity

Life, Relationship change

Because Thor and Steve cannot be trusted with earth's best interests and Spiderman is more mature than most people give him credit for.

While the Homecoming stuff is happening in the background, Tony and Stephen establish their truce between science and magic while Gretal is just so done with their cautious nature around each other and proves that they can trust each other by unleashing a symbi (which did not exist and involved hilarious experimenting in Gretal's and Ku's part [Again, another truce between assholes] and also involved Wong because why not) and letting them catch each other.   Only for her to catch the both of them for some reason and boom, new Holy Trinity. You'd think Peter would geek out about that but even he's tired of their endless ogling and have been waiting for this moment where they all three got together and became earth's mightiest heroes.   Ends with a christmas more lively than last year's, Tony thought he'd be celebrating alone again but now he has a family with him.
