RBG catching the DS plan Q suggested watching her comings and going for signs of activity=easy  But it's not about "her" comings and goings, it's about who makes themselves present at her home prior to and during oral arguments! Does she have lawyers coming in, or retired judges? Her voice scripts, if being dubbed, are based on her past comments and arguments.  If she's incapable of responding, the DS would have to provide assistance on where to look, at what cases she worked and how she responded.  It would be great if another judge, on the oral argument panel, could ask a question, perhaps interrupt, where she'd have to respond personally based on one of her past obscure cases.  But if lawyers, retired judges are at her home days before and during when she's giving an oral argument, that would be very telling and would put in question her need of 1. legal backup, 2.  perhaps show there's a biased position being offered by other then herself, 3.    another legal mind is interfering in the oral arguments of which she is to be completely independent.  The DS watchdogs have to be with her when oral arguments are taking place.  Someone has to coach her ahead of time or be prepared with dubbed comments, but they have to have someone present for that" just in case moment".If she has 'visitors' during that time frame, it would put her comments in question, which may allow a proper investigation into her health.
