Forgive me if this has already been covered but I've noticed something throughout Season 7. Patrick Stewart is little more than a cameo in several of the episodes. A little bit at the beginning and/or end. Was the reduced screentime in his contract? Also, I've noticed he's almost always sitting during his cameos. Was he hurt or sick when the filming was taking place?
) There does seem to be a bit of a phenomena in tv of the main cast of a show taking a break as the show wears on.
