As Ben left the sunken remains of the Second Death Star, Han nodded to himself.
Then Luke appeared next to him.
"How did you do that?" the translucent Skywalker asked.
"Do what?" Han replied, glancing back at him. "Turn him back to the Light?"
He shrugged. "I guess second time's the charm, huh?"
Luke sighed.
"Not that," he said.
"Then what, kid?" Han asked.
"This," Luke replied, waving at Han. "Being a Force Ghost."
"Why are you asking that?" Han replied. "You're doing it right now. Surely that must mean you know how to do it better than I do, you're the one who's a Jedi."
Luke rubbed his temples with a sigh.
"What I'm getting at," he said, slowly, "is that you're here. When you shouldn't be."
"Oh, do I have an appointment somewhere else?" Han asked. "I dunno, my schedule's pretty full."
"I mean as a Force Ghost!" Luke told him. "Which you must know, you're not quite this dim."
"I seem pretty bright right now," Han said. "What's the problem with it?"
"It's a Jedi thing," Luke explained. "And, furthermore, it's more of a thing for certain specific Jedi."
"I don't see the problem," Han shrugged. "I'm a Jedi."
Luke stared at him for several seconds.
"You are not," he said, firmly but calmly, for which personally Luke thought he deserved another medal.
"I am by marriage," Han defended himself.
"That's not how it works," Luke groaned.
"Really?" Han challenged. "How do you know?"
Luke raised his hand, then stopped, then lowered it again.
"I'll… get back to you on that once I have an answer," he said.
AN:
That's not not how the Force works. He should know.
