Hi there! I'm KC, and I've got Ron Weasley, Tony Stark, and the 11th Doctor. Obviously Ron's head is going to be spinning over being older than his mother, and I'm here for it.
As for Peggy, my headcanon is that Peggy was Tony's honorary nephew, and that the Stark and Carter families were close. Lena and I have been playing Tony and Sharon with that in mind. Is that cool with you? I find it hard to believe that with Peggy's relationship with Howard and Jarvis, she wouldn't have been around when Tony was growing up. Because, awwwwwww.
