It could be that Natasha has a special surprise for Peter after picking him up. She might take him to a new training facility that she has set up just for him. There, she can start teaching him some advanced self - defense moves or show him some cool spy gadgets. This would be a great bonding experience for them, and Peter would be super excited to learn from her.
Well, maybe they'll go for ice cream on the way home. Peter could start chatting about his day at school, like how he aced a science test or had an interesting discussion in history class. And Natasha would be all ears, giving him some advice here and there based on her own experiences.
Perhaps when Tony picks up Peter, there's some sort of danger lurking nearby. So they end up having an impromptu adventure on the way back. Tony could show off some new gadgets to Peter to deal with the threat.

Well, it could be that Peter picks Morgan up on his skateboard, which Morgan is super excited about.

Then, when they get home, they play a fun game together in the yard.
Well, they could go for a walk in the park and talk about their latest adventures. Percy might share some crazy story from his time at the beach, and Annabeth could tell him about a new book she's reading. Maybe they'll stop at their favorite ice - cream place and just enjoy each other's company.
Perhaps it develops as they face challenges together. For example, if some villains target Peter at school, Natasha is there to protect him.

One possibility is that when Annabeth picks Percy up, they run into some minor mythological creature that's lost in the human world.

Peter could be really worried about his identity being revealed while he's sick. His weakened state might make it harder for him to control his powers. What if he accidentally shoots a web in the middle of the classroom? He'll have to be extra careful, and this internal struggle could add a lot of interesting drama to the fanfiction.
