Interesting how she calls The Handmaiden "Slayer of her own Kin". One thinks it has do with what happened with her half sisters, but if the theories regarding Kreia are correct, it has additional meaning here.
Bao-Dur is not present in this cutscene because, originally, he was meant to die while helping HK-47 find the HK Factory back on Telos IV. That was cut from the final game, along with the HK Factory itself (Wich you can only play if you install TSLRCM). Also, Bao-Dur is the only companion, besides the droids, whom Kreia/Traya cannot predict its future.
With AI voices now a thing on mods, I think this scene will be much better if they incorporate more dialogues, not by VA, but through voice synthesizing.
