Every now and then Martin gets an opportunity to write something that might normally feel out of place in the series. His prose tends to have some flourishes of course, but you can tell when he really gets to have fun. The septon monologue in AFFC comes to mind first, and after reading this chapter we can add those mummer stage scenes to the list. It's thick with Richard III references. The entire chapter was amazing of course, but I found myself almost wishing the POV perspective could stay in the theater just to hear more.
The first thing I thought of when I read ADWD's prologue back in 2011 was that Harys Swift would run into Arya; someone on Reddit called it
even more accurately. He has survived so many books despite being a dumbass lmao but it seems like his luck is running out.
So I guess Arya was going to play Sansa in the play?
