SEASON PREMIERE: This new season begins with some shuffling of the deck, regarding both the personal and professional situations of the characters we’ve come to know and, if not love, at least love to watch. That goes for Michael Sheen as uptight sex researcher William Masters, and it certainly goes for the only two cast members nominated for Emmys this week, star Lizzy Caplan as Virginia Johnson and recurring guest star Allison Janney as Margaret Scully.
