Mega Buzz: Which Familiar Faces Are Returning to Masters of Sex — And Why?

There's no rest for the weary on Masters of Sex.

With Bill (Michael Sheen) and Virginia (Lizzy Caplan) having at long last published their book, it's time for the next step in their endeavor: trying to make a bit of money off of it.

Though the meeting may not lead to exactly the kind of collaboration Bill's hoping for, it does lead to a renewed partnership with an old pal: former Wash. U. provost Barton Scully (Beau Bridges), who's now in a relationship that will prove quite surprising to longtime viewers.
