- Never Say Goodbye: The whole point of Michael concealing the fact that this is his last day. Jim is the only one to realize what's going on and confront him. Michael then tries to say a proper goodbye to him, only to quickly begin tearing up and Jim cuts him off to say they should just say their goodbyes at lunch tomorrow.

- Train-Station Goodbye: Pam makes it to the airport to say goodbye to Michael.
- Weight Woe: Deangelo reveals that he used to be overweight and has been carefully monitoring his food intake since then. However, it's clear throughout the episode that he's only barely fighting the urge to snack on sweets throughout the office, and at the end of the episode he practically has a breakdown as he keeps tearing off pieces of Michael's goodbye cake and screaming at it, leaving the rest of his new subordinates horrified.
