Nigel Ratburn, Serenity Sweetwater, Francis Haney, and Miss Tingley are all involved in a love square that begun on November 12, 2014 (A Date to Remember). Ratburn and Sweetwater went into an inter-species relationship sometime before September 17, 2014 (Ratwater, Part 1). Haney and Miss Tingley also had an inter-species relationship that seems to have begun around or before August 28, 2014 (Undercover Principal, Part 1). The two couples both had to keep their relationships secret, because inter-species relationships were highly frowned upon and seen as taboo. The two couples revealed their secrets to each other on September 17, 2014.
On February 12, 2015, an event known as the "switcheroo" occurred. During the Inter-Species Revolution, Miss Sweetwater was slapped by Mayor Hirsch during a fist fight, and she fell to the ground, injured. After Mayor Hirsch was killed, Nigel Ratburn rushed to Sweetwater's aide. Haney and Miss Tingley watched in fright from the side lines. Sweetwater muttered, "only true love's kiss can save me". Ratburn kissed Sweetwater, but it did not work. To everyone's surprise, Haney run up and kissed Sweetwater. This time, it "worked". Sweetwater apologized to Ratburn, and broke up with him. She and Haney are now in a relationship.
Later, Ratburn and Miss Tingley wanted to make Sweetwater and Haney jealous, so they went into a fake relationship (Hanewater).
