Anakin watches, smiling softly.
And, over the coming weeks and then months and years, she stays by Rey's side, training her. In self mastery, in the Force, in philosophy (after a lot of internal debate, Anakin presents the Jedi Code and all its complications as one remembered philosophical text out of many - let Rey learn old treatises on love even as she learns old treatises on proper uses of the Force), in history (Anakin steers clear of her personal history for now, focusing instead on things she learned as a padawan), in politics (Anakin glows when she talks about all her children are doing in the New Republic), in logic and decision making and responsibility, in science, in math, in art, in fighting and surviving and playing -
Anakin's had a long, full life. Four years gives a lot of room for her to teach. It's not everything. Not enough.
Slowly, she opens up about her family, too. Talks about Luke and Leia and Leia's two children, about Han Solo, about disappointment and worry and love - always love, Anakin loves more intensely than anything. She died for love, she says once, and love binds her still.
Luke's re-founding the Jedi. Anakin has opinions about how he's going about it. She's proud of him, though, woven in with every worry and criticism and praise.
Leia's not as central to the government as Anakin thinks she should be. She's got a lot of support, though, and she's getting a lot done.
Ben and little Anakin (Anakin has a laugh at the name of Leia and Han's younger kid - "Hope it's not prophetic," she says, "I wouldn't wish a second me on the world.") are training under Luke, too, and the original Anakin talks about them enough that Rey probably knows them about as well as she knows anyone.
