The police detective asks Sophia if she remembers an event that happened in September of 1985. After a sarcastic comment, in which she says she doesn't, Dorothy reminds her that she came to live with them on that date due to the Shady Pines fire. However, in the pilot Dorothy remarks to Blanche, who wants to borrow her stole, that it's Miami in June and only cats where fur. Since Sophia comes to live with the girls in that episode it's stands to reason that the Shady Pines fire was in June not September.
