My apologies if you answer this already. But does Draco have a patronus? And if Draco doesn't have one, what will be the ideal one?
Draco doesn’t have a Patronus. JK has stated that at least by the sixth book, he couldn’t conjure one because it’s not a skill readily taught at Hogwarts. Some sites go more in depth, saying that it’s because he doesn’t feel anything positive strong enough or whatever, but that’s all she’s said on the matter that I can find, so we’ll leave it at that.
And I don’t think we’re really qualified to say what his “ideal” Patronus would be as we don’t know him personally. (He’s a fictional character yo, the one who knows him best is his creator). Our Patronus represents our happiest thought, and according to JK, they often correspond between couples (James and Lily with the stag and doe, Hermione and Ron with the otter and jack russel terrier) as the love of our life is often our happiest thought. So if I had to guess, it might have something to do with Astoria (his wife).
