“Are you my real father?” hit like a truck because Leia Organa is tremendously powerful in the Force, some part of her remembers her mother, just vaguely, but she does. “She was beautiful, kind, but sad,” Leia says in Return of the Jedi. She remembers that day on Polis Massa in some way, just brief, fleeting memories, but she does.
“Sometimes when I look at Luma, I see her mother’s face. We all miss her very much.“ rings with so much truth in the Force that Leia, with her ability to see into people, to know when they’re lying, to read them like an open book, knows that’s true.
Somehow, he knew her mother. From there, it’s not a big leap to, “Are you my real father?”, it’s a reasonable conclusion, if the wrong one.
But some part of her feels it, too. Because some part of her must remember him as well, Obi-Wan was there that day, even if she may not knowingly recognize him.
If Leia remembers her mother, she likely remembers Obi-Wan, too.
