for Tommy before attempting to investigate, finding Frank in a secret lab before she is cornered by both Frank and Eve. On Earth, the Dodos seem to lay eggs which begin ticking. At MOTLO, Eve reveals that while Frank had been cloning the animals mainly to make a profit, she had realized that since planets ended all the time and species died, her collection would never be truly complete so she plans to have the clone dodos lay bomb eggs which when detonated would destroy the Earth and will then hold Martha in her collection as the last survivor of Earth. The Doctor returns to MOTLO, attempting to hold Eve at stalemate with a ticking Dodo egg, which fails. Upon being told the plan, the Doctor points out it wouldn't work as since the Universe is constantly expanding, by the time Eve finishes killing off one civilization, billions more will have already been created, meaning her collection can never be complete. Faced with this, Eve shoots herself, revealing herself to be an android, and the Doctor is able to disable the bombs from her. Attempting to find out Eve's codes so they can retrieve the displaced animals, the group is confronted by Frank who plans to use one Dodo egg to destroy MOTLO and escape with his cash. Dorothea manages to bury the egg in Frank's bag before he teleports away. Tommy reveals he knows Eve's password and the Doctor transports all the animals on MOTLO back to their original time periods. Dorothea is introduced to the Dodo clones which have remained behind and the Doctor advises the MOTLO workers to possibly document the creatures another way.
