Peter Parker has been living in Stark tower with all the other Avengers for a while now, and he loves it there. Then one day at school he receives a permission slip for a field trip to his own home! (I know this trope has been done a million times before but! It's a good trope! I think I can put a bit of my own spin on it anyway. Also, Peter Parker is autistic and you can pry that headcanon from my cold, dead hands.)
