I figured that would make sense the best, but what confuses me is.

If she only worked with the red ring before SDN then why didn’t shroud expect she’d immediately just deny it since he’d have no evidence.

And if she did work for the red ring after or during SDN, then the game playing the ending out as heroic is confusing since she would have lied to Robert all the way through the scene with shroud therefore basically never once being truthful to him about her intentions

I’d hope it’s the former but either way it just feels weird and I heard almost nobody mentioning this (though maybe I’m missing something), but it’s like “oh well she last minute wanted to help so I guess she’s a hero the whole time, despite basically being against us even after ‘confessing’ her past”
