Two new British agents replace Madison's drama with their own
Drama level: 2
Volume level: 2
Without Madison, there's no more three-way drama between Heather, Josh Altman, and Madison, and the show doesn't quite know what to do with her this season, in the same way she doesn't seem to know what to do every time the camera is on her.
Although Heather she's now an agent herself, "Million Dollar Listing" has spent more time on her impending wedding with Josh, because that's consistent with the general sexism with which the show has treated Heather, always as the property of one male character or another (see: her interaction during previous seasons with Madison). Also, girls are supposed to care about weddings.
However, she did lock Josh out of the house and give him the finger, which is pretty much what viewers want to happen to him all the time.
