- Throughout the series, Emily gets angry the rarest out of Clifford. Her only angry moment is in Jetta's Sneak Peek, when she discovers that her diary was read by Jetta Handover (who was so eager to peek that she did not ask for permission). In the prequel series' episode "My Blankie," she also gets angry with Nina over finding out that the latter had told a secret about her baby blanket to one person, because every person tells another up to the point where Mr. Solomon dedicates a book on baby blankets to Emily Elizabeth.
