Now all I can think of is little Ben reacting to Leia telling him that Uncle Luke is her brother like ????--kind of like when you're a kid and you're told your grandparents are your parents' parents, and it just doesn't compute AT ALL because, no, they're just Grandma and Grandpa, they're nobody's parents. Or maybe that was just me. :)

There are three Solo kids instead of one in the EU, and I'd just love the possible dynamics you could get with another Solo sibling in the movie universe...my first thought would be a sister, and her either staying with the light or following him would both be such interesting options. I'm kind of leaning towards her going darkside as well, though? Because then they could have this super-interesting dynamic, because, say, she was younger than him, and her following him after the debacle at Luke's temple was one part believing the message and one part just being a scared little kid who's going to follow her brother because he's her brother, where else is she going to go? So in that way she's more of a survivalist than an idealist, and grows up much less devoted to the cause than he is. And Ben killing Han could also really up the tension between them.
