Exactly. So, in the film, you have the line, “Weak. Like your parents.” If you could find a good instance of Palpatine saying “to”, you could make the line, “You’re too weak”, or just “You’re weak”.

It would be simple enough to change the line, “Only you have the power to save them” to “Only I have the power to save them”. You have lines like, “Long have I waited”, “I never wanted you dead. I wanted you here…”, and “That is what I want”.

For, “She will take my power”, you have the original line, “She will take her revenge”. There are several instance of him saying “my”, like when he says “my spirit will pass into you”. You also have the line “She will take my life”.
For the word power, you have “Only you have the power to save them”, “A power like life itself”, “The power of two restores the one true Emperor”, and “A scavenger girl is no match for the power in me!” The emphasis on that last line might fit the best, if you can isolate it cleanly enough.
