Well, I don't think it would be a flashback so much as it would be one of those hazy edged memories featuring no more than Padme's face. Okay, not literally hazy-edged, but you get my point. It would be like some kind of quick flash to a shot of Padme's face while Leia says the line about her mom being beautiful yet sad.
