I think her belief in God will be one of the bigger parts of her  character arc. I was actually hoping Scott would touch on that with  making one of his characters beliefs so intense that no matter what she  sees on this planet it doesn't make her psyche weaker but turns her  faith into a weapon by causing her to sink more into it as events grow  much harsher as it acts as a self defense mechanism if you will.
It's possible that the other characters who may seem stronger physically  in the beginning end up being wasted early on because they start losing  themselves in the madness of whatever they encounter on that planet  without anything to hold onto like Noomis character.
Also I think what will shake up the characters psychologically the most won't exactly be the beings trying to eat them (
although I'm sure that'll be part of it) but rather the secrets they uncover in relation to that human like head.
