Leah reunited with her brother

She was found in the woods by Jim and Lieutenant Washington, along with other soldiers. After being brought back to Terra Nova, she stayed with Jim and Elisabeth Shannon. At first Taylor and Jim thought Leah was not a Sixer spy, just a girl looking for home. It was later found out that Leah was sent by Mira to recover a box hidden in the floor in the house where Mira lived when she was at Terra Nova. After being caught by Jim and Lieutenant Washington at the fence she is then questioned and it is found out that Leah's brother was being held captive by Mira. She and her brother were later adopted into the colony and taken care by a woman who came on the Third Pilgrimage. ("The Runaway")

During the Harvest Festival, Leah rehearsed for the role of "Lieutenant Washington." ("Vs.")


  • Broke into the house that used to be Mira's to recover Lucas's box in order to hand it to Mira.
  • Played the role of Lt. Washington during the Harvest Festival play.


Leah is aloof when she arrives at Terra Nova after leaving the Sixers' camp out in the jungle and wasn't used to taking showers.


She's very caring about her younger brother Sam.
