Morty and Cass come closer to completing their character arcs in this office scene. At the start of UTC, Morty considered Cass his rival. In Chapter 3, Morty came to realize the error of his ways and made an honest effort to restore Cass, but his failure simply made Cass so angry she decided she would invert their relationship and become the means of Morty’s destruction. This was basically a balancing act: instead of going right to being on the same side, the characters overshot their targets and went to the opposite extremes. Here, they begin to settle into their final roles as peers.
