Note: Here is a bit more I have written, to give some more context to Ben and Anakin's reunion.
Chapter 10
Four years later.
Anakin was hard at work repairing his moisture vaporator with his half-brother Owen next to him. Padmé tended to their children who were insisting on running around. Anakin exchanged a glance with Owen Lars.
"Pop's getting told old for this Anakin." Owen said.
"But we can handle it." Anakin replied.
"My nephew and niece are quite a handful."
"That they are." In the distance, a strangely familiar figure came toward them over the horizon. Anakin sensed a familiar presence.
"Who is that Anakin?" The young Jedi was shocked at who he saw. It was Obi-Wan Kenobi.
"Ben." Anakin dropped what he was doing and ran toward his old friend. They embraced. "What are you doing here? How did you find us?" Obi-Wan Kenobi smiled at him.
"You are going at covering your signature my friend." He paused for a moment. "But it was your handiwork that let me know you survived the Purges." Anakin's eyes widened.
"Are the younglings all right?"
"Yes…yes…they made it out in the escape pods. Where they are however is an entirely different matter." Anakin turned away from his old friend.
"It's my fault Ben…all of this. I let him kill Windu. He almost turned me into a killer." There was compassion in Kenobi's voice.
"How could you have known who Palpatine really was? None of us knew until it was too late. Do not blame yourself for your mistakes and missteps. You proved yourself to be a fine Jedi Knight. You did the right thing."
"I had to go into hiding…" Anakin said sheepishly.
"I know. We all did." Something caught Kenobi's eye. He saw the figures of Luke, Leia, and Padmé. "Are those…" Anakin smiled.
"Yes, they are children. You need to meet them. They need to know their Uncle Obi-Wan." The two men walked together as if nothing had changed in the intervening four years.
