About Time (I) (2013)
Incorrectly regarded as goofs
This entry is not a valid "Goof". The changes made to sperm producing "Girl Posy" mattered, as Tim had already loved and "knew" Posy. She had a history and personality that Tim was not willing to change. Tim visiting his father before the 3rd child's birth does not negate the reliance of that plot point, though. Tim's last visit with his Dad takes place before #3's birth. As such there is no ingrained gender or personality for Tim to fear losing. Yes, it could alter the baby, but not in any way noticeable to Tim.
