Tony Stark is really a son of Hephaestus, Clint Barton is a son of Apollo and Natasha Romonova is a daughter of Athena. But none of them realized that the others were demigods until Apollo flashes in, Natasha and Tony kneel. Clint is confused about how they know who Apollo is, until he realizes they are demigods and freaks out asking stuff like "Who's you parent?" and stuff like that. Then Natasha realizes what hes talking about and says "Athena. I'm guessing Tony's is Hephaestus and yours is Apollo. Am I right?". Tony then realizes what they are talking about and nods and suggests that they go to camp as none of them had been there since the second war. Later the rest of the Avengers are confused as to where they when't because they can't find them. When Tony, Natasha and Clint get to camp they go to see Chiron then surprise their siblings. When they get to the big house they walk in on a counselor meeting. No one notices them except Chiron, but when Natasha puts her finger to her lips in, he just lightly smiles and keeps talking. They sneak up on their respective cabins counselors and hug the behind while whispering boo. They all freak out but when they realize who it is they get excited and flock and hug them. They stayed there for a while until they had to leave, but swore on the Styx that they would come back as soon as they could. and with that, the left. When they got back to the tower the rest of the Avengers asking where they where and why the had lightly ripped up shirts and burn marks (sword fighting and the lava wall). They didn't answer. The end.
