Season 13, Episode 7 - "A Messenger in Despise"
Roz stumbles upon Noel and Bonnie making out in the broom closet and agrees to keep it a secret until they are ready to tell people. When Noel and Bonnie make Roz their official “messenger” to each other when they’re apart, she begins to get sick of it but keeps it up because she feels guilty for invading their privacy. When Noel calls her out of a meeting for something “urgent”, Roz decides to exact revenge, and delivers a message to Bonnie saying “I love you” to stir things up. However, Bonnie is delighted, and Noel is unsure of why he is getting so much affection from her all of a sudden. Meanwhile, Gil campaigns for a new refrigerator in the lunchroom after the outdated model fails to keep his expensive food cool.
