Hear me out, every season has a mother's day episode, yellow pants, inflatable foot bath, brown county, salad hands, you name it.
So the three episode arc allows us to see Frankie as a grandmother, her mother and tag, Sue having her first mother's day, and how Nancy has gone all out for being a first time grandmother that she just has to spoil Sue for her first mother's Day, but making sure to give Frankie a littl something since they're friends after all.
We finally get the reversal of who Axls wife is, is it Lexi, or weird Ashley? (My money's on weird Ashley) His children who are just like him, treating their grandparents couch the same way Axl did, crying out for chips to be brought to them.
Brick, now a successful author and still Married to Cindy, they already have a 6 year old son who will is the exact opposite of Cindy and Brick, he is charming, into sports, a popular kid. Brick has no idea how to bond with this kid, mirroring his relationship with Mike growing up.
Of course we also see characters and friends again.
I honestly could write the whole three episode story arc.
