Ahh I was hoping somebody mentioned this.
I'm behind but finally watched the HBO series. I was shocked to see the "Watchtower" featured in the episode.
The funny thing to me that isn't mentioned here is the reference to pandas. The character mentioned the pandas in trying to witness to a guy. Then his girlfriend overhears him and says to him "tell me about the pandas."
To me there was a JW very involved with the writing of this episode. I kid you not but I actually studied with a girl who picked up tract off the ground with the panda on the cover, and she became a JW.
Anyways, I listened to the podcast about the episode and the writers mentioned that the character was a "Jehovah's Witness".
Good series. Now I get it.
