* He's not in danger: The Director is a character who has been brainwashed by the Team Rocket. He is not being held captive or threatened.
* He's the antagonist: The Director, under Team Rocket's control, is actually the one you need to defeat in order to stop the broadcast of the Rocket signal.
* You defeat him: After you battle your way through the Radio Tower, you will face the Director in a battle. He will use a powerful Pokémon, but you can defeat him and save the day.
To progress through the Radio Tower, you need to:
1. Travel to the Radio Tower: This is located in Ecruteak City, after you've obtained the 8th Badge.
2. Battle your way up: You will encounter various Team Rocket grunts and trainers along the way.
3. Face the Director: After defeating the other trainers, you will reach the top and face the Director, who will be using a powerful Pokémon (likely a Scyther).
4. Defeat him: This will stop the Rocket signal and complete the Radio Tower quest.
