As I stated in the old thread, I'm pretty sure Frankie never had an IF of her own, not because she lacked the creative ability to make one but because her parents wouldn't allow her to have one. As for why, we can only guess. I admittedly have no proof that my idea is in any way correct; it's just a feeling that somehow feels right to me.
