Showtime’s “Masters Of Sex” premiered a shocking episode on Sunday. In Season 4, episode 6, Betty’s pregnant girlfriend delivered a child and died. Even with Dr. Barton Scully performing the caesarian and Dr. William “’Bill” Masters scrubbing in later, Helen could not be saved. The episode ended with Helen’s parents taking the child home. Betty didn’t even get to hold her daughter.

What will happen in episode 7?

“Masters Of Sex” Season 4 will see Bill (Michael Sheen) work with Art (Jeremy Strong) after Virginia/Gini (Lizzy Caplan) refuses to work with him. It looks like she somehow learned that he convinced his wife they slept together on the night of the coats or keys party.

In a sneak peek video (embedded below), Gini tells Bill that Art and Nancy (Betty Gilpin) should work together while she and Bill reunite as work partners. She tells him that she just wants to work with him and has no ulterior motive.

However, Bill suggests something even better: He work with Art while she work with Art’s wife Nancy. Since she can’t come up with a valid reason not to work with Nancy, she has no choice. This new work partnership will be interesting to watch since Nancy and Gini had a showdown last episode.

The official synopsis of the upcoming episode on “Masters Of Sex,” titled “In To Me You See,” reveals that Bill will groom Art to be his protégé in a new area of research. Meanwhile, Gini will try her best to keep Nancy at arm’s length.

Elsewhere, a sad Betty will seek an unlikely source for help in acquiring equal rights to Helen’s baby.

A sneak peek also shows Gini and Nancy working on their first couple together.

“Masters Of Sex” Season 4, episode 7 will also introduce fans to Dody, Bill’s former lover.

“Masters Of Sex” Season 4, episode 7 premieres on Sunday, Oct. 23 at 10 p.m. EDT on Showtime.
