In the episode “Oasis” (April 3, 2002), the Enterprise discovered a crashed ship that they felt could be scavenged for parts. When searching the ship, the Enterprise crew discovers a whole team of people hiding out onboard, including a man named Mural. Mural was played by René Auberjonois, a “Star Trek” regular who also played the role of Odo on “Star Trek: Deep Space Nine,” and who had a small part in “Star Trek VI: The Undiscovered Country.” Mural had a young daughter named Liana, who had been raised on the crashed ship.
Over the course of the episode, various crew members are taken hostage by the crash survivors, as they require Enterprise technology to survive. Other crew members will also discover that there doesn’t seem to be enough food in the crashed ship’s greenhouse to feed as many people as they have seen. The twist in the episode will reveal that only Mural and Liana survived the crash years ago and that Mural, a skilled engineer, had created all the other characters as holograms. His ultimate goal was to ensure Liana was raised in an environment surrounded by people. Capt. Archer (Scott Bakula) gives Mural and Liana the necessary repairs to escape the planet.
Wersching was stoked to play the part of Liana, happy with the knowledge that a “Star Trek” veteran and long-working actor like Auberjonois would be playing her father. She admitted as much on her Twitter account in 2019, speaking out in sympathy when Auberjonois died. Having come from theater, Wersching had no experience acting for cameras. Auberjonois, it seems, taught her a lot. The lessons clearly took, and Wersching enjoyed two decades of television work.
