mLiquid. I beg to differ. No enemies in the area at all and here is what happens.
Quizzy active, press HOLD
Make Varric Active Press HOLD
Make Solas Active Press HOLD
Make Iron Bull Active Press HOLD
so far all good, they all stay put where I put them BUT then it fails entirely.
Make Quizzy active and,without doing anything, no moving, no interacting, nothing, simply make Quizzy active, Quizzy gets ran over by Varric, Solas and, Iron Bull rushing to his side. No that is not what HOLD means. It means stay unless we travel or get attacked, or Quizzy leaves the immediate area at least. No one was in danger of dying, nothing was attacking anyone Quizzy didn't even move and yet HOLD released for no reason. All in one room with no NPC's nothing to mess it up and force them to move. Hence Dead hands Puzzle impossible since for me HOLD fails entirely the moment I make Quizzy active again. Same if I make anyone active other than Iron Bull or, if I move Iron Bull at all, they come unglued for no reason. Thus the Dead Hand Puzzle is impossible, change active and, that one gets rushed by all of the others. You can't do that puzzle that way.
