While looking at this, How did Hermione catch Rita Skeeter?, it mentions that it would be kinda hard for Rita Skeeter to respond to Hermione as a beetle. This got me thinking:
How did Rita ask the questions to the Slytherins as a beetle? As in that scene where Draco is holding her in his hand, and talking to her.
"Come and look at this," said Ron, who was standing by the window. He was staring down onto the grounds. "What's Malfoy doing?"
Harry and Hermione went to see. Malfoy, Crabbe, and Goyle were standing in the shadow of a tree below. Crabbe and Goyle seemed to be keeping a lookout; both were smirking. Malfoy was holding his hand up to his mouth and speaking into it.
"He looks like he's using a walkie-talkie," said Harry curiously.
"He can't be," said Hermione, "I've told you, those sorts of things don't work around Hogwarts. Come on, Harry," she added briskly, turning away from the window and moving back into the middle of the room, "let's try that Shield Charm again."

"When we saw Malfoy under that tree..." said Ron slowly.
"He was talking to her, in his hand," said Hermione.
