Great Barrier
Ella and Zach are in a department store buying a business outfit. After trying it on, Ella does a model walk up to the window and poses. It is later revealed that the outfit was a disguise that would be used while stealing from a jewel store. Ella was disguised as a Japanese businesswoman and Zach as her translator.

After they steal three jewels, they throw away their outfits, and Zach dies in the middle of the thoroughfare. Goren and Eames trace him back to Ella, via the store clerk, and realize that the two of them were serial thieves. After further research into Ella's behaviors, such as the posing in the window and the frequent checking of her phone, they learn that someone is orchestrating her crimes.

A description from a witness causes them to realize that this someone is criminal mastermind, and serial killer Nicole Wallace, who has gotten away with all of her crimes until this point, and is the nemesis of Detective Goren. Nicole has a very bizarre relationship with Ella, as it is somehow motherly, and adulterous (although both of these are merely to manipulate Ella into committing crimes for her). Nicole even manipulates Ella into attempting to stage a fatal asthma attack on her ex-husband Gavin Haynes. After finally tracking Ella down, Goren finds Ella is very difficult to phase, until Eames learns that Nicole wanted Gavin dead because he knew about her past.

Goren reveals Nicole's secret to Ella: years prior to the series, Nicole killed her toddler daughter by snapping her neck. She also killed her accomplice Mark Bayley by poisoning him, and attempted to kill her husband/lover Gavin. After intimating that Nicole has a habit of killing her children, lovers, and accomplices, Ella realizes that she is all three. This convinces her to wear a wire to get Nicole to say something incriminating, as there is no actual evidence to tie Nicole to anything. However, after the staged meeting transpires, Nicole realizes its a set-up, and kills Ella by throwing her from a window before faking her death.
