[4][5][6] She and Ackerman broke up in the early 1940s (originally over her continuing to smoke, though that spat was quickly settled)[7] and remained estranged until her death.

Together with then-boyfriend Ackerman, she attended the 1939 1st World Science Fiction Convention (Nycon or 1st Worldcon) in New York City dressed in "futuristicostumes", including green cape and breeches, based on the pulp magazine artwork of Frank R. Paul and the 1936 film Things to Come, which were designed, created and sewn by Douglas.

Fans liked the concept, and the 2nd Worldcon, in Chicago in 1940, had both an unofficial masquerade held in Morojo's room and an official masquerade as part of the program,[11][12] with participants (besides Ackerman and Morojo, who performed a brief skit in the costumes they had premiered the year before) including E. E. Smith, Cyril M. Kornbluth, Jack Speer, Wilson Tucker, Robert Lowndes and David Kyle.

In 1941, at the Denvention (3rd WorldCon) she wore a frog-faced mask devised for her by a young costume maker named Ray Harryhausen.

She was married three times: to Virgil Van Buren Smith, Henry Willis Gray, and, lastly, to John Arthur Nolan.
