Peter Parker

Peter works with his father, Tony Stark.
Peter had never seen Tony's daughter because, according to Tony, they wouldn't get along, but in reality, Tony was just jealous of his daughter.
One day Peter was talking to Tony about some meeting when Morgan, Tony's daughter, showed up.
She went to Tony to let him know she was leaving for the mall.

Tony Stark: Okay, you can go. I almost forgot. This is Peter, Peter, this is Morgan.

Peter: Nice to meet you.
They greeted each other and she left.

Peter: She's beautiful...
Tony: She's my daughter!
Peter: Oops... Sorry Mr. Stark, I didn't know she was your daughter.
