"I'm failing to come up with a mental picture here." She's been neglecting to do her crunches for too long; she starts up again before Ms. Finch comes over to investigate. "One person knew about your existence, did not manage to name you, and yet presumably however fast you grew you spent some time roughly child-sized and some possibly different amount of time child-competent and this means he managed to keep you, at minimum fed. And you randomly have a British accent, which could be a later affectation, I guess, and I'm not an expert at identifying fake accents, but my first guess wouldn't be that you developed it watching television. My next attempt at deduction is that he had some kind of help."
"Before he created me, he wrote a fully functional artificial intelligence program, whom he named Jarvis. Jarvis spoke with an English accent, although not precisely the same one I use, and he was my main companion for most of my accelerated childhood."
"Did Jarvis have the wherewithal to feed you when you were little, or did he just remind Tony?"
"By the time I was old enough to form lasting memories, Tony did not need much reminding. Although I learned to cook as soon as possible after that, because he was consistently terrible at it."
"That explains that, I guess, not that having learned how to cook needs particularly much explaining."
"She keeps telling me that I should come over some night for dinner. Perhaps I should take her up on it."
"Oh, is that where I put it?" he says airily. "I might have set the house on fire. I probably wouldn't have killed you."
"Of course it's where you put it, although I hope you don't expect me to figure out which toe. Why wouldn't you have killed me?"
"Well, no, I couldn't have been coerced into getting through the wards for you if I were dead," she acknowledges, "but, alive, I had - continue to have - the ability to tell on you."
