Professor Dumbledore was having his worst time ever as headmaster. If Harry was right (which Dumbledore knew he was) Cedric Diggory was possessed by Lord Voldemort until he could find a way to separate the two he placed Cedric in a stasis charm so neither Voldemort or Cedric could cause any harm. The downside to this was the owls that kept on coming, from the ministry, from the governors, from the Triwizard officials and from frightened parents about their sons and daughters.
Suddenly the door opened.
"Who's there" Dumbledore demanded drawing his wand.
"An old friend" the invisible figure said heartily as it appeared.
"James?!" Dumbledore exclaimed hardly believing his eyes.
"But..." Dumbledore for the first time in ages was lost for words.
"I'm dead?" James questioned.
"I actually am alive"
Dumbledore, suspicious because James was dead, asked.
"If you really are James Potter.." Dumbledore began.
"Do you really think I'm a death eater?"
"No... I"
"What is this? 1981?"
"It is you James" Dumbledore said. He knew It was James because no one else would make a joke in such circumstances.
"Where is my son?" James said sternly.
