The wheels are properly coming off for John Sugden. Although Mack worked out he's Nate's killer, John's dealt with him, but others are starting to smell a rat... including Aaron.

Back from their break, John learns that Charity is thinking about reporting Mack as missing. Spewing an excuse, he rushes out. It's yet another red flag for Aaron.
