Character Analysis
In this film, Hagrid is still the same friendly giant we've always known, and he still has a slightly unsettling affection for terrifying animals.
In fact, that love ends up playing a kind of big role in Harry's efforts to get Slughorn to reveal his secret about Voldemort. Slughorn, Harry, and Hagrid end up hanging out/drinking after holding a funeral for Hagrid's "friend" Aragog (a terrifyingly huge spider that you might remember from Chamber of Secrets).
Sure, Hagrid is pretty much asleep when Harry gets the secret out of Slughorn, but if it hadn't been for Hagrid and Aragog, Harry wouldn't have gotten the opportunity to get Slughorn drunk and wear down his defenses, right?
So, thanks, Hagrid.
