“It’s pointless.”
How appropriate. The show returns to this knock knock joke from the beginning of the season in “Ten Thirteen”, this time telling it in a Meg context as she sits on a bench with Evie. It’s a dumb joke that also plays as a nihilistic statement, as an encapsulation of many of the storylines of the show. It’s the central statement of Meg’s storyline, one that has become increasingly prominent as time has progressed.
