I think there's a good chance that Snape is not a Voldemort supporter. Rowling is not that simple. She would never make Snape the villain because we have spent too much time suspecting him. It's likely that a bigger twist awaits. Similarly, I wouldn't count Malfoy as a true supporter either. The way the scene is set up, it looks like Malfoy is more afraid than supportive of Voldemort. Lastly, there is more to Dumbledore than what meets the eye. We know that he is the only wizard that Voldemort fears and we also know that he has said that his presence will always remain at Hogwarts to those who support him, so I woudn't be surprised if we haven't heard the last of him.

Does anyone suspect that Dumbledore might be in league with Voldemort?

Did anyone think that it was strange that Harry, Ron, Hermione didn't suspect that Voldemort was the half-blood prince? Am I missing something or was that a plot hole?
