Harry is preparing to get in his Firebolt. Hedwig's already plugged in.
Albus. Harry. You must complete the training.
Harry. O. I can't get the vision out of my head. They're my friends. I've got to help them.
Albus. You must not go.
Harry.But Ron and Hermione will die if I don't.
Ghost. You don't know that.
Enter the ghostly form of Sirius Black.
Even Albus cannot see their fate.
Harry. But I can help them. I feel the Magic.
Ghost. But you cannot control it. This is a dangerous time for you. When you will be tempted by the dark side of the Magic.
Albus. Yes. Yes. To Sirius you listen. The cave. Remember your failure at the cave.
Harry. But I've learned so much since then. Professor Albus. I promise to return and finish what I've begun. You have my word.
Ghost. It is you and your abilities the Dark Lord wants. That is why your friends are made to suffer.
Harry. That's why I have to go.
Ghost. Harry. I don't want to lose you to the Dark Lord the way I lost Snape.
Harry. You won't.
Albus. Stopped they must be. On this all depends. Only a fully trained Auror Knight, with the Magic as his ally, will conquer Snape and his Dark Lord. If you end your training now, if you choos the quick and easy path, as Snape did, you will become an agent of evil.
Ghost. Patience.
Harry. [angry] And sacrifice Ron and Hermione?
Albus. If you honor what they fight for, yes.
Ghost. If you choose to face Snape, you will do it alone. I cannot interfere.
Harry. I understand. [climbs onto Firebolt] Hedwig. Fire up the converters.
Hedwig. [whistles]
Ghost. Harry. Don't give into hate. That leads to the dark side.
Albus. Strong is Snape. Mind what you have learned. Save you it can.
Harry. I will. And I'll return. I promise.
The Firebolt takes off into the sky.
Sirius' ghostly form fades.
Albus. Told you I did. Reckless is he. Now . . . matters are worse.
Ghost. That boy is our last hope.
Albus. No. There is another.
The Firebolt disappears into space.
