Flower makes multiple references to chatting many times with Patience, the ghost who was left wandering the grounds. But in Holes Are Bad (2024) 2 episodes earlier, where Patience's existence was revealed and Flower was recovered from the well - which would be after all such chats - Patience's mere existence was news to Flower, Flower didn't know about her. (Flower's memory of Patience here is far too strong to dismiss this as her usual forgetfulness).
