He attempts to cast a Memory Charm on Harry and Ron using Ron's damaged wand, but the spell backfires and leaves him with near-total amnesia. In Order of the Phoenix, Harry comes across Lockhart in St Mungo's while visiting Arthur Weasley at Christmas. Lockhart has not recovered any of his memories, but is childishly proud of being able to write in "joined-up letters". He still enjoys signing autographs and continues to receive fan mail, although he has no idea why. For his part, Harry feels a slight twinge of guilt for Lockhart's amnesia, but he consoles himself with the fact that it was Lockhart's own fault.

She speaks approvingly of Lupin's prescription of chocolate to alleviate the effects of a dementor's presence on students, commenting that Hogwarts has "finally got a Defence Against the Dark Arts teacher who knows his remedies". In Goblet of Fire, she treats Harry twice; once for a dragon strike and
