Rachel’s endgame wasn’t simply to get Frigg to show her power where someone else could see it, but to get her to understand– physically, which is how Frigg understands things– the nature of this power, feel it flowing through her and not just acting as a Lego attachment to her weapons or granted her by some outside force.

With her mission accomplished, Rachel not only has no more need to fight, she has no more frustration to fuel her. Her faith has been rewarded already.

There’s no question in my mind that she means this dialogue in the moment. She’s not eager to die and she doesn’t think that she will– she believes in Frigg’s goodness, too– but she knows death or grievous injury is possible, here. She’s given her all to what she knows was right, and she accepts whatever the world will offer her in return.
