No great surprise it was Beatrice and, as I predicted, this is part of the process that Beatrice has planned to make Hannelore ready to take over Elicott-Chatham Incorporated. It's also in-character that Tilly is so dehumanised in Beatrice's mind that she's hard-pressed to even remember her name (despite the fact that I bet she personally vetted Tilly for the job).
I find myself wondering who is going to have the most eye-opening personal experience over the next 48 hours - Hanners or Tilly!
Quick question....why is Beatrice shocking Thirty/Thirty?
I think that the 'telescopic neck' thing is probably an indication that the AI in the robo-horse is defective. If I were to guess, it would be that Beatrice deliberately agreed to have this defective unit as it gave her an excuse to regularly and legally use painful means of restraint and control over a sentient creature whilst being able to claim self-defence.
Because she's evil. Seriously, that's the only reason. Beatrice is a Lawful-Evil personality and she really
does get personal fulfilment from hurting people, dominating and controlling them. She really is a
very bad person.
