She reappears later in the same episode, imprinted with a military persona directed to forcefully extract Echo and a client from a hostage situation.

Apparently speaking of the client she insists that she "[has] to help her", but her words take on a double meaning as she is shown to be staring at a picture of Sierra.

In enacting her plan to rescue her fellow Active, Echo repeats Sierra's earlier remark, although her imprint ought not remember it: "Friends help each other out.

In "Gray Hour", Topher and Boyd Langton observe that the three dolls have developed the habit of eating lunch together at the same table every day.

Boyd wonders if they may be remembering each other, but Topher cites "herding instinct" and compares them to bison, flocking together in instinctual survival patterns that go deeper than memory.

[4] Through "True Believer" and "Man on the Street" Sierra and Victor are shown to be developing a sexual attraction in their mind-wiped state.

Further investigation finds that she has been crying in her sleeping pod each night, and a medical examination reveals that Sierra has had sexual intercourse while in the Dollhouse.

It emerges that Sierra is an Australian artist called Priya Tsetsang, who sells her work by Venice Beach in Los Angeles.

In an attempt to seduce Priya, Nolan commissions a large painting from her and arranges an elaborate showing of the finished artwork in his house.

To further impress her he employs the services of the Dollhouse, which sends Echo and Victor to the showing, both imprinted to enthuse about Nolan to Priya.

Some time later, the Los Angeles Dollhouse is searching for a new Active candidate and has located a young, apparently-paranoid schizophrenic woman who appears to meet their specifications.

The woman is revealed to be Priya, and her debilitating mental condition has left her a patient in a psychiatric hospital run by Nolan.

Topher assumes these claims to be a part of her schizophrenic delusions, and Priya is brought to the LA Dollhouse to become the Active Sierra.

Topher is only driven to investigate Priya's history further after being confronted by Echo, who presents him with a painting of Sierra's dominated by a threatening black shape.

As an Active programmed to desire him, Priya cannot reject Nolan's advances, and since her entry into the Dollhouse he has been hiring her for frequent sexual engagements.
