And why didn’t she forbid them from developing the personalized virus? Or take the eggs back? All that “You wouldn’t do this if you loved me” dialogue feels completely unlike the Carol we’ve seen all season. At this point, we need a spin-off just to explain what happened during those 40 days of solitude.

I agree that she probably should have asked (and may have did offscreen). I think they’d refuse. It would contradict their priority which is infecting Carol.
