An interesting glance into Ro's past. Not just a glance, but also an opportunity to see how she
reacts to all that. She definitely doesn't like herself. I wonder if in the result of that experience, she'll change and work on her personality and choices not to make so many mistake any longer. It was a chance for her to analyse her own decisions and actions.
I must say, though, that the format didn't serve well that part of the story. Not the script format, but to time limitation of such a script format (after all, it shouldn't be longer an one-hour episode). That re-discovering of her own self would work much better if it took more time than one day. It would have a stronger impact both on Ro and on the readers. It just felt too superficial and too rushed.

is a very interesting plot twist. So it's not just hallucinations, but a serious medical and mental problem.
