One big mystery: who is Linda? We only know that she is implied in War (maybe veteran), and she needs a wheelchair. Somebody says she is Richard Horne´ sister but I have only suggestions of it.
Otherwise, Audrey is missing until new happenings.
11/18 chapters scheduled and Audrey is not in the screen? I can´t believe it.

Audrey was one of my favorites and I anticipate her return with every new part. It's possible Linda is her daughter. We've had so few clues that Linda could be anybody at this point.
