Out of all the ideas listed so far, the ones I'd throw my vote behind, fwiw, are:
1. NS' concept of making the ability to deal with Riya into a nod to the real personal influence PC has earned besides their status as Vic's kid.
2. Kesil's idea of Spess Prison is the one I like the most. The role just fits her very much, and power 'abuse' + handcuffs are a major part of her fetish set. Like, Penny might goof about such things, but with Riya it will fit the interests of the TA like a glove.
3. Dzaan cum or Red Myr Venom addiction I'm not so keen on, but if it can be done in a way that won't kill Riya's character, having her still be dommy/assholish to some extent, I can't deny that I find the concept pretty hot. I also have a vague idea about combining it with # 2. Like, have the Chief Warden of the Spess Prison (or other kind of potential Riya's superior there) be a Red Myr morph/Dzaan that isn't amused at all with the attitude of officer Batra apply their special disciplinary touch on Riya, with mixed results.
Now, to list the ideas I'd love to see and that weren't mentioned:
1. Linking the resolution with the Report Her option. It will immediately solve the issue of 'trap option' a decent amount of people brought up.
2. The idea of Riya's situation being the result of a compromise between her friends and foes upstairs, PC learning about the arrangement and then using that information in combination with their newly gained influence.
3. Having an option to send Riya somewhere PC will never see her again alongside an option like Spess prison. That way, those who want nothing to do with Riya period will be able to get rid of her for good, and those who want to have more of her with a changed dynamic will be able to do have such content.
4. Expanding on shade's idea, Riya being down on her luck and allowing a caring dom to take the lead for at least a bit, tho in my mind the dom in question shouldn't necessarily be the PC (they'll just witness and maybe participate) and Riya should have a lot of her attitude still intact (think sub!Sera, but more butch).
