The Doctor sat calmly in the grand vampire court, surrounded by Dracula and his loyal subjects. The air was thick with tension as the king of the vampires demanded to know the whereabouts of his teenage son, Logon. Dracula's eyes glowed red with anger as he awaited the Doctor's response.

The Doctor, a Time Lord with a keen sense of diplomacy, met Dracula's gaze with a cool confidence. "Your son is alive and well, King Dracula. He is currently with the Avengers, Earth's mightiest heroes."

Dracula's expression softened slightly at the news, relief washing over him. Logon was his pride and joy, the future king of the vampires. He trusted the Doctor's words, knowing that the Avengers were powerful allies who would protect his son.

The vampire court murmured amongst themselves, intrigued by this unexpected turn of events. The Doctor quickly explained that Logon had been drawn into a battle between good and evil, where his unique skills and abilities were greatly needed.

Dracula nodded in understanding, his mind already racing with plans to reunite with his son. "I will do whatever it takes to bring him back to me, Doctor. I owe you a debt of gratitude for delivering this news to me."
