Re: Ahsoka's relation to Luke in Imperial Problem Child-verse. Luke's training lineage further confuses things. He starts off under Obi-wan, which makes Luke Ahsoka's lineage uncle and Anakin's brother. Then he goes to Yoda, which means he's Dooku's lineage brother, Obi-wan's grand-uncle, Anakin's great-grand-uncle, and Ahsoka's great-great-grand-uncle by the Jedi lineage rules as we know them. Plus I'm sure he picked up somethings from Dad Vader, which makes the whole thing even messier.
Someone found Han trying to work it all out once with a stylus and a piece of flimsiplast. Leia put two painkillers and a glass of water on the table when he got to Obi-wan.
Luke brought hot chocolate when he got to the Dooku thing.
Han is really hoping that if he and Leia have kids someday (big “if” there, flyboy, first you have to tell her you love her he thinks, as if it weren’t blindingly obvious to everyone), explaining it to the kid won’t be as nightmarish as working it out on paper.
