While I am not a fan of the Wards route..I do not like the Wards route. It's boring. One chapter for power testing, one for saying hi to the Wards, and one for the great reveal that Magpie is now an indentured servant of the PRT. All comedy coming from Wards being exposed to Addy won't be anything new. We already had that from Taylor, Lisa, Anette, and Danny.
Malicious compliance also won't get her anywhere. PRT has a huge stick in form of her tinkering budget and approval of her projects. Annoy them and she gets scraps and nothing she builds from them will get approved. THEN there's the fact that they already got their money's worth out of her by forcing her to build dress spheres for them. Anything else is just a bonus. Finally, she has to stay there for years and PRT will make sure that she does. Just to keep their dress spheres working.
Overall, Addy just gave up her agency in exchange for absolutely nothing. All she had to do to get out was Null Lance her head and respawn at her base. Problem solved. PRT can have all the fun proving that the new hero TottallyNotMagpie is actually Addy.
She could make the dress spheres set to malfunction. And say that's a built in feature.
Just mention all the crap they pulled in interviews. Stripping a traumatized pre teen girl after she was kidnapped and even changing her panties for her while she slept is a scandal at best.
Publically mention Eidolon getting weaker, then bribing her way out or at least never telling gg them how to fix it.
Taunt em with knowledge, maybe drop that Jack slash is a Thinker with some master components online.
Just to verify her info.
Depending on how specific the contract is on timing She could resign as soon as she's unveiled.
She doesn't really need any of their supplies. So this could just be a short arc.
