1] The logline frames the prince as fleeing from negative forces instead of struggling toward a positive specific objective goal. (“Quest for redemption” is vague and subjective.)

2] And there is nothing in the logline to indicate why he needs to be on a “quest for redemption” — what’s his flaw? It’s the old man who has a “murderous past” — not the prince. And it’s no sin to be pursued by a “dark temptress”; it’s only a sin to give in to temptation.

So why does he need to be on a “quest for redemption” when there is nothing in the logline to indicate what evil he has done or sins he has committed?

Richiev:

I like where you’re going with the internal journey; she did the right thing — for the wrong reason. She fulfilling the her job description, nothing more.

But I don’t think you need to use flashbacks: just re-create the same subjective problem in her post-amnesiac state-of-mind That is, she has a 2nd chance to learn what she didn’t learn earlier, to help with a heart (metaphorically speaking). Perhaps her failure to give a “divine damn” was why her antagonist was able to betray and defeat her earlier.

And,now, in her post-amnesiac situation, she initially recapitulates her earlier failure-flaw. But this time, finally, thanks to the influence of her sidekick she learns to do the right thing for the right reason. When her sidekick’s life is at stake: she saves the sidekick character physically; the sidekick character saves her subjectively-spiritually.

fwiw.
