Delores is a mannequin that Number Five refers to as his partner when he lived in the post-apocalyptic future. When he returns to the present, he asks a truck driver he meets at Griddy's Doughnuts for directions to the department store where she is displayed, so he can get her again. He later accomplishes this and is ambushed by Cha Cha and Hazel, but he manages to get away with Delores.
In the van that Five uses to stake out the eye manufacturer's building while Luther is requesting that Five go to the academy to talk about what to do with Grace (Mom) Klaus is seen holding Delores closely even stating "We're really hitting it off back here."
Delores is also seen with Five when he is drunk in the library after Cha Cha and Hazel light the prosthetic eye business on fire. Then Delores is carried by Five who is carried by Luther back to Diego's place in the boxing gym.
While Five is in the apocalypse Delores is shown wearing different attire depending on the season. In a "dialogue" with Five, it is stated that Delores's favorite wine is a Bordeaux. Delores is also shown to think that apocalypse Five drinks too much.
Later, Luther uses Delores as leverage when Five announces his plan to kill Milton Greene in an attempt to stop the apocalypse. In order to get the gun from Five, Luther drops Delores out the window. Five warps down to catch her, and Luther manages to get his gun.
Delores is later seen at the bar in the Hargreeves' home when Hazel comes to talk to Five, and relinquishes his and Cha Cha's handguns to clear Diego's name as a suspect in Detective Eudora Patch's murder.
Five returns Delores to the department store and says his goodbyes. On his way out, he asks an employee to give her something new to wear, adding that "she likes sequins."
