After learning that Aunt Edie has passed away, the Hecks board a train with the body to take her to her final resting place in South Dakota. But along the way, Frankie accuses Mike of not being very caring or nurturing after she trips in the dining car and is helped up by another man, while Mike continues pumping out some ketchup. Axl believes that he was responsible for Aunt Edie's death because he had used the excuse that his Aunt had passed away numerous times to get extensions on his school assignments, Sue attempts to complete her college entry essay and accidentally sends it before correcting an inappropriate sentence and Brick decides to take a risk and live outside his comfort zone by befriending a complete stranger in order to live his life as freely as his late Aunt did.

The Heck family learns about Darrin's marriage proposal to Sue.. as well as her response. Meanwhile, Axl attempts to use his intro to Psych class to cure Brick of all of his quirks and tics.
