"Sloth to Slay" focuses on Thomas Diggs, a shy 20-year-old computer gamer who lives with his older sister Krissy and spends his spare time gaming. His mother passed away when he was 11, so it's been him and his big sis for a while. Nicknamed a "sloth," he's fallen into routines and built up walls over time. This season three episode doesn't necessarily roll out all of the tear-jerking moments, but it's subtly affecting. Anyone who's fallen into a routine or felt too shy to reach out to people can relate to Thomas. With help from the Fab Five, Thomas prepares for his 21st birthday, making anime-loving friends and picking up a Donald Glover-inspired swagger along the way.
