Walky’s last line is kind of hard to parse, even if you remember what he’s about to do. Hell, even I had to suss it out a bit. However, without spoiling, I will remind y’all of the thrust of each of their arguments with each other.

1) Joyce thinks Walky will do anything to resist a potential relationship with Joyce (‘cuz he’s chickenshit)
2) Walky thinks Joyce is still hung up on other guys she used to like.

Long story short, Walky believes he’s gonna do something to prove both of these items true.

Meanwhile, Billie hilariously interrobangs at Joyce’s casual ability to fly like it ain’t no thang.
