Olga appeared in "The Tale of the Thirteenth Floor". She was portrayed by Susan Glover.
Olga is a member of a race of Blank Faced Aliens, a peaceful and friendly group of aliens. Ten years prior to the events of the story, she and her robotic husband Raymond visited Earth. In which during this time, they mistakenly left their infant daughter behind when returning to their home planet.
Then in the year 1993, she and her husband had gathered enough of their planets atmosphere to visit Earth once again to rescue their daughter. She and her husband contacted with their daughter through messages on t.v. (in which their daughter Karin kept mistaking for dreams).
She and her husband and their friend Leonid, rented the entire thirteenth floor of the apartment building.
They set it all up with colorful games and gadgets. They invited her to come up and visit it (under the pretense that it was a new toy company), and that she was invited to come test the toys. The truth was, these were just gadget and machines designed to help Karin come back to her senses and regain her true powers before returning home.
During this time, she Raymond and Leonid used minimal amounts of their atmosphere. This was done so that she would appear as a normal humans and not scare her. However, Karin didn't believe them and still had no idea what was going on. Karin eventually used a remote control, and ordered Raymond to hold her in place. Karin then escaped with her brother and made it back to the apartment.
Then just after her spaceship took off, she contacted Karin on the T.V. again. She wasn't mad or frustrated, she was calm, polite and patient. She nicely explained to Karin that she was her mother. Also their trip was supposed to be her rescue. Because ten years ago, she accidentally left her behind when returning back home. She then explained that since their mission failed, they won't be able to come back again for another ten years. This was because the supply of their planet's atmosphere ran out and it was essential.
Then she breathed in the last of her atmosphere. This turned her back true blank alien form and she wished Karin goodbye promising to see her again in ten years.
