When Roy takes Paula home, as he is leaving he picks up a copy of the Assassin's Creed video game.

Jen strongly objects to the idea of co-workers Roy, Moss, and Richmond coming into her home in a casual setting. However, in Aunt Irma Visits (2006), Roy and Moss come to her apartment for a "girls night" and Jen later wakes up at home to find Moss in her bathroom.
When Jen reminds Roy and Moss not to keep talking about memory and RAM, Moss says "Memory IS RAM!" The converse is true, but "memory" in the strictest sense could mean ROM or RAM. Moss should know that.
