So he asks me to tell him about the toys every now and then.
It would be pointless for me to rehash all the entire movies and everything. He'd get bored. So I tell him about each character that he asks me about. He asked me about Darth Vader a lot. So I told him the saga of Anakin Skywalker, how he turned to the Dark Side of the Force, and how he was finally redeemed in rescuing his son.
When the Little Fayoumis plays with his Luke and Vader action figures, now, the phrase "I know what's behind the mask!" features in the dialogue extremely often.
I approve. It's like fanfic, in a way, and he's getting a look at the universe from an angle that he might never have considered if he'd only restricted himself to the way the movies looked at the characters.
