By Season Six, Willow has become an extremely powerful witch and permanently "de-rats" Amy simply by conjuring an incantation. The two become friends again, though Amy now seems to be drastically different from before she turned into a rat. The character had apparently been involved with the warlock Rack before becoming a rat. Amy gets Willow involved as well, leading her to become addicted to black magic. Later, when Willow decides to give up magic, Amy casts a spell on her, causing her to magically manipulate everything she touches for a while; Willow complains that Amy's actions are encumbering her attempts to quit magic. Amy responds by mocking her, implying that she did it as revenge for being trapped as a rat for years. As a result, Willow cuts Amy out of her life entirely.
