Tooth of "Crimes"

Maybe my mind was wandering during the Roundabout's fine-but-not-great revival of Beth Henley's Crimes of the Heart, but at some point in the second act, I perked up when Babe, wanting to cut an article out of the newspaper, says:

Where are the scissors, Lenny?

With the current production of The Homecoming still fresh in my mind, the line made me wonder if Henley had read her Pinter, or if it's just a coincidence. Then, more recently, watching MTC's intent revival of Come Back, Little Sheba, I noticed that one of the leads is a man who picked up the nickname "Doc" because he'd once pursued a medical career, and who retained the nickname even after his plans to become a "real doctor" (he's a chiropracter) hit the skids due to personal excess. With a few key differences of geography and bad fortune, this also roughly describes one of the male characters in Crimes.

Certainly there are accidental--or, if you wish, synchronicitous--resonances throughout the dramatic literature, and I really have no larger point to make here, except to note the way that theatregoing can start to feel like a dialogue between plays as much as between characters.
