Ok, so Topher thought he could help Sierra by giving her memory back and send her to confront with Nolan. She ended up stabbing Nolan like a bad piece of steak. Not that Nolan didn’t deserve it, but Sierra had to return to being a doll since she didn’t want to live with the memory of being a killer.
Pria said it was like waking up from a nightmare to live in one. When Topher apologized to Pria for not simply letting her go free, Pria said she would have went to confront Nolan anyway. Which is true, when the actives were given the chance to resolve what bothers them, Sierra went to confront Nolan.
So what could have Topher done to actually be of help?
I don’t think brain washing her to love Nolan and give her live away to Nolan for ever is helping her either. Maybe Topher can program Sierra to fake horny long enough to tie Nolan up and feed him live picked boogers… or is Nolan such a perve that he might enjoy that?
