Rearview Mirror - S1.E4

Mike learns that Kyle, a guy who bullied him in school, is now in prison. Shunning his father's advice, Mike decides to pay Kyle a visit (with Martina in tow) to show him how well his life has turned out. This inspires Stella to meet up with a nerd she once bullied named Elliot so she can apologize to him, but it leads to something else.
