Leia and Rey see the force ghosts of Luke and a woman with red hair holding hands.
Rey says, "Who's that woman with the red hair?"
Leia whispers into Rey's ear, "Mara Jade. She's Luke's wife. She was an Emperor's Hand. Like you, she's Force sensitive and had something to do with Emperor Palpatine. She is a Jedi. For a while she worked in smuggling. "
Mara whispers to Luke, "Who is the girl with Leia?"
Luke says to Mara, "Her name is Rey. Leia is training her as a Jedi. I started her training."
Rey says, "Hello Mara."
Mara says, "Hi Rey. I heard you are being trained as a Jedi."
Rey says, "Luke started my training. Leia is training me some more to help me become a Jedi Master."
Mara says, "Good job, Rey. You will continue the Order. Make me proud..." The ghosts fade away
