Chekhov's Gun in season 3

I love how in season 3 there are so many tiny Chekhov's guns in it- except for the literal gun, the one thing acknowledged as a possible issue later is actually never used.
A few off the top of my head are the keys in the cage, the bow and arrow, Marriene (kind of), the "If you have a problem with another man, fight" thing from the hunting trip (Joe immediately has to fight), the substances in the sex bag, the flowers in the garden.. and just so many other little things like that.

Maybe it's dumb but I just love that little detail.
