You guys this isnt monas brain...its hotchkiss technologies. This company created beacon guard, they specialize in security and surveillance. thats why they are able to view everything that is happening on all of these screens. Mona is still working for them. Theyre comminicating with mona through mirrors.
Note: mona seemed shocked and wasnt expecting nolans death. She asked HT is this our fault? And they tell her to go to her safe place as if they are trying to control mona. Maybe they are not filling mona in on everything they are doing. Maybe they used mona for her skills to help with the techology and game design for their own agenda.
