As the offspring of an Andorian and Aenar, Talla had a skin of a paler blue than that of a regular Andorian. Unlike the Aenar, however, Talla had seemingly fully functional eyesight.
In 2161, Talla was kidnapped in the middle of the night by former "associates" of her father. Her father enlisted the help of his old friend Jonathan Archer in rescuing her. The mission was successful, and Talla was unharmed during the ordeal. (ENT: "These Are the Voyages...")
It is highly likely that Talla was named for LieutenantTalas, whom Shran was romantically involved with before her death in 2154.
