Hermione Tries to Prove Eileen Prince is the Half-Blood Prince

Hermione Granger passionately argues her case that Eileen Prince could be the Half-Blood Prince, explaining that if Eileen's father was a wizard and her mother a Muggle, she could be a “half-blood Prince.” Harry, however, dismisses Hermione's logic, stating that he's certain the Half-Blood Prince is male, based on how the spells were written in the book. Hermione leaves in frustration, determined to find more evidence.
