I don’t think however that Anduin’s arguments should be what convinces her though.
They can shake her a bit, but if she truly believes that she is powerless, then despite what Anduin is saying she isn’t the one with the power in that room. The Jailor has power. The Arbiter system she thinks damned her has power. She doesn’t “hold the power” if that is her world view, and thus she should commit to her current path. Even if she hesitates atm.
Frankly, if the Jailor (and not the Arbiter, like she believes) is who’s actually responsible for dragging her into the Maw (and her Primes were playing her), then that reveal should be what both shatters her world view and what gives her the proper catalyst to get on a redemptive path. Not the sleepover musings of Teen Heart-throb Young Brad Pitt here. No matter how dreamy and hope filled his blue eyes are lol!
