>She seems devoted to Loki in spite of hating him.
Did you fags skip the ranger sign bravo story and the few scenes in the main story were loki and fenrir were alone? Fenrir and Jade were made by a laboratory looking to make Primals as expendable tools of war, hence them modifying Jade into a suicide attacker after she was unsuitable for their primary purpose.
Fenrir and Jade were failures, weapons that couldn't be used and were fated to be discarded. Loki accepted Fenrir and 'used' her despite her flaws, that's why she's "devoted" to him, there's no other astral left to rescue her so her redemption would involve breaking the brainwashing and making her see herself as a person and not just a primal beast(tool) to be used by an astral.
