^Nah, Lursa and B'etor would have manipulated the father. There's no way Lursa would get herself pregnant without being sure she'd still have power.
Agreed. Whoever the father of Lursa's child is, he was probably just a pawn.
In fact I wouldn't put it past Lursa to actually have killed the child's father after he outlived his usefulness to her; Lursa certainly does not seem capable of any kind of feelings of romantic attraction, love, or even compassion. She is utterly cold.
