AU idea 1/2: What if Loren were recruited to be an Ellimist figure like how Crayak tried to recruit Rachel? Longer pitch: it frustrates me that Loren is so clever and resourceful and badass but in #49 she's basically reduced to "nice middle aged lady who remembers nothing." So it would be a satisfying twist if she had superpowers and took Elfangor out of retirement and before he can decide what to say she's like "I know everything you know plus a whole bunch more. Here's what you need to do."
AU request part 2: I specifically have a joke in mind about "I'm a traditionalist- I believe women should engineer spacetime and men should take care of the kids." Here, "take care of the kids" means he either goes to help the boys out with whatever the hell The One is or helps them deal with the trauma from all they've been through. I imagine some kind of therapeutic/rehab vegetagble garden for them to work in, but your imagination is better than mine and I'm sure you could rock it. :)
So to be honest, Loren's not my favorite character for all the reasons you just mentioned. She's frustratingly passive in #49 - #53, and Ax's narration in #52 comments on her not putting in much effort to build a relationship with Tobias. She's also not my favorite as a kid, mostly because she comes off as, to be blunt... spunky.
Anywhoo, I'm tossing this one to fellow fandalites in the hope that someone is willing to weigh in with ideas.
