Sounds more like Stockholm syndrome and trauma bond to me. A father-daughter relationship between these two is just unbelievable.
A father-daughter relationship, even in a dark story, involves:
Maul provides none of this. No signs that Maul views her the same way.
(Sidious himself actually does this criteria to Anakin, to manipluate and groom him into his long term broken sith apprentice for decades. Personally, it would have been more interesting for Maul to be subtle and charm and less overt to manipluate Devon. It would make her heel turn in the finale feel more believable.)
What Devon experiences resembles more of coercive control and trauma bonding and survival‑based attachment.
-Devon is a rebellious, impressionable teenager who wants justice against the Empire, and Maul exploits that. He exploits her anger, her sense of injustice, and her misery, the same way Sidious once preyed on his.
- he isolates her through kidnapping and coercion from her master that she genuinely loves, and then through external circumstances of the Inquisitors forcing thrm to work together.
- he controls her environment
- he alternates cruelty with “kindness” like good advices and speeches and that tea ceremony scene and protection from Inquisitors.
- He removes her support system by getting Daki killed by Vader. He knew how important Daki was to Devon.
-Willingly to use the Force on her to control her mentally and physically and will lash out at her whenever she pushes back.
- In the end, Devon is just isolated. He becomes the only remaining one left after her master is killed off because Maul made it that way. He shapes her grief into purpose. (Makes no sense to why that Devon herself doesn't deduce that Maul had a hand in Daki's murder by Vader.)
