Harry ends up under her care quite often. In "Philosopher's Stone", he spends three days unconscious in the hospital wing after the confrontation with Professor Quirrell. In "Chamber of Secrets", he spends one painful night regrowing bones in his arm, after Gilderoy Lockhart vanishes them, much to Pomfrey's vexation. In "Prisoner of Azkaban", she tends to Harry twice; once after the Quidditch match against Hufflepuff and once after the Shrieking Shack incident. 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 once after the confrontation with Voldemort. In "Half-Blood Prince", she tends to Harry after his skull is cracked by a Bludger in a Quidditch match.
