Dollhouse: Where Are They Now?
4. Dichen Lachman
Priya was an artist whose wealthy donor became obsessed with her. After failing to seduce her, the donor kidnapped her and pumped her full of enough drugs to make her seem like a paranoid schizophrenic. Using his connections to the Dollhouse, he presented her as a patient and had her enrolled as Sierra. The creep then kept hiring her with a more pliable version of Priya inserted into the doll, so that he could live out his fantasies.
When this is revealed in the show, we see Sierra suffering from her encounters with her kidnapper despite not holding the memories of their encounters. She starts painting dark pictures, prompting Victor to collect the black paints in the Dollhouse and flush them away so that they can't upset Sierra anymore.
After the Dollhouse shut up shop, Dichen's next big role was as Suren, a vampire in the American version of Being Human. Roles in Last Resort, The 100, Shameless, Agents Of Shield, The Last Ship, and Altered Carbon followed over the years. Dichen is currently involved in Jurassic World 3 which is set to release next year.
