By the end of Past Perfect, the playwright seems to have abandoned his interest in mother-child relationships. Dina is often present on stage, but her sphere of influence considerably weakens in favor of more predictable plotlines focusing on Seth's relationship with Charlie and Betsy's with the bottle. Even Jake the tumor seems to have more clout.
Ultimately, it's almost as if Dina never gave birth. I wouldn't be surprised if the character gets to take her revenge in a future Silver play as a violent, childless harpy.
