Luke is found and raised by Vader on Coruscant, though not turned to the dark side (at least not yet.) He's kind of brainwashed and he does love his dad, but he's also still very much himself, gentle and friendly and kinda whiny but very sweet. He has an awkward, ambivalent relationship with his position in the Imperial hierarchy that he mostly tries to avoid thinking about while he's still young enough to avoid it, but theres less and less avoiding he can do as he gets older and he's kind of a political figure.
Leia is a senator and a secret Rebel agent. She expects to hate Vader's son, until she actually MEETS him, and... and then she really, really doesn't.
