Check out Part 18 of this Harry Potter and the Deathly Hallows Part 2 walkthrough and beat "Lost Diadem" with this online demo. Hermione: Harry, where's the horcrux? Harry: The ghost of Helena Ravenclaw, she told me the diadem was hidden here. I can feel it. Draco: That's my wand, Potter. Harry: I don't think so. Its allegiance is to me now. You want it, you'll have to win it back. Goyle: Come on, Draco. Don't be a coward. Just do him. Crucio! Watch your back, Potter. We'll be waiting. Ron: Harry, you okay? Harry: I'm fine, but we'll have to keep an eye out for them. Hermione: Come on, let's find the diadem. Draco: Serves you right. Hermione: You might as well show yourself, Blaise. Draco: Potter, you have something of mine. I'd like it back. Harry: What's wrong with the wand you have? Draco: It's my mother's. It doesn't understand me. Don't get used to that wand. You won't have it for very long. Ron: No pressure, mate, but we've got some really unpleasant company. Any sign of this diadem thing? Harry: It doesn't feel very close, but I think we're going the right way. Hermione: Ron, you do know what a diadem is, don't you? Ron: Hermione, of course I do. It's the. . . what we're looking for. Hermione: There we go. Ron: Brilliant. Goyle: Hello, Potter. Draco: Wait, don't wreck the room. This diadem sounds important to him. Goyle: What's that matter? It's Potter the Dark Lord wants. Who cares about a diadem? You bludger! There's plenty of places for us to hide in here, Potter. Ron: That's it. Draco: Potter came in here to get a diadem, so that must mean. . . Goyle: Must mean? Who cares what you think? I don't take orders from you no more, Draco. Harry: Expelliarmus! Goyle: Draco should've done you when he had the chance. This ain't over, Potter. We'll hand you over to the Dark Lord, Potter. Then you'll be sorry. Ron: What's that? Hermione: Don't worry, I think it's fine. Ron: Do you hear Goyle and Draco? I think they've fallen out. Harry: Yeah, and Goyle seems pretty dangerous. Hermione: Okay, I'll move it. Harry: Get back! Hermione: Harry, it's Draco. Draco: Give me my wand, Potter. Harry: No, I don't think so. Ron: No! Draco: You still have my wand, Potter. Harry: Get lost, Malfoy. Stupefy!
