In the Volume 3 issue The Zorkbo Files, Zorkbo describes the details of how she and Morris met. During a dog show sometime before Elwood, Morris notices crop circles and otherworldy designs in a cornfield. Zorkbo's ship is hovering overhead, and she reveals that she is an alien from Zionica sent as ambassador to Earth. Morris then asks her out for coffee.
Morris and Zorkbo's relationship was briefly revealed in The Baxterette, Part 2 after Morris' failed date with Bitzi Baxter. In Aliens Among Us, we see the details and hardships of an alien living on Earth. Morris was wary of bringing Zorkbo out in public, for fear of causing a panic or even someone taking her away from him. They had a close call at the General Store when Zorkbo's hoodie fell off, exposing her to the shoppers.
While on a drive somewhere outside of Roswell, Morris and Zorkbo's car is hit head-on by a government SUV. Zorkbo is kidnapped by the government and brought to Area 51, where they attempt to perform tests on her. Morris tries to save her, but Zorkbo's time has come: she chooses to depart this planet (A Galactic Farewell).
