Continuity mistake: When Carrie and Steve are sitting on his front steps discussing Aiden, Carrie is looking forward as Steve says "He lost his ability to open up and trust women." At that moment; Carrie turns her face towards Steve to her left, and keeps it there as she is appalled. But the very next shot; Carrie is suddenly facing forward again, and then starts turning her head left towards Steve for a second time. But in the next shot; she is already facing Steve, from the first time she reacted to what he said. It's clear that she had never actually moved her head after the first time.
