Washington Black (TV series) introduces Tanna Goff as a quietly assertive and richly complex character in her very first scene. In Washington Black, Iola Evans portrays Tanna as the biracial daughter of the accomplished scientist G. M. Goff, torn between her father's demand that she "pass" as a child of England and her own wish to be herself.
The series places her struggle with identity, which takes place during 19th-century Nova Scotia, not only as personal drama but also as a viewing window onto colonial racial expectations playing out in Washington Black. In the series, Tanna's own story grazes more than romance; it's a subtle examination of identity, scientific fascination, and insubordination.
Her growing bond with Washington "Wash" Black, along with tensions from her father and societal expectations, structures a complex narrative, both personal and reflective. The series, out in July 2025, provides a richly textured depiction of Tanna's internal and external struggle, and thus her arc is one of the series' key components.
Tanna Goff in Washington Black: Casting and character foundation
Tanna Goff comes to life through British actress Iola Evans, who worked with personal experience and emotional truth. Evans used her own biracial (Kenyan and Welsh) experience to relate to Tanna's inner conflict of concealing and claiming her Black heritage.
According to Marie Claire, she underlines that Tanna
"It was nice to play a character who just wants to be her whole full self, which is like, Why can I not be that?”
This encompasses the essence of the show's description of her yearning for authenticity.
Identity and resistance
Tanna's own identity in Washington Black is not simply her own conflict; it's a counterpoint to her father's frame of mind. Mr. Goff urges her to hide her mother's heritage to preserve social class, portraying herself as a "child of England."
But Tanna refuses that effacement, demanding,
“Why can’t I be more?”
This is an early turning point in Washington Black that frames her search for self-expression.
Relationship with Wash: Mutual recognition
Tanna's relationship with Washington Black is based on recognition and artistic collaboration. Wash is a creative and inventive spirit that enables her to see new horizons, and she is able to see and admire him in ways others do not.
Their relationship, from artistic collaboration to profound emotional intimacy, becomes the core of the series' narrative. The plot employs this relationship to delve into themes of vulnerability, belonging, and mutual comprehension.
Love triangle: Security vs selfhood
A central conflict of Washington Black lies in the love triangle between Tanna, Wash, and the wealthy Billy McGee. Billy, set up by Tanna's father, promises security, but not the depth of emotion Wash brings.
This dynamic highlights Tanna's personal conflict: deciding between a secure but limiting identity and a dangerous but true bond. Evans spoke of this dichotomy, highlighting how Wash is the first character to ever really see Tanna.
Authentic collaboration, symbolic presence
Though the series is rooted in adventure and discovery, Tanna’s story is grounded in authenticity. She contributes to scientific efforts through her perspective and insight.
Every aspect of Tanna's arc is firmly anchored in her actions, interactions, and decisions as seen throughout the episodes of Washington Black.
In Washington Black, Tanna Goff is a quietly incendiary presence, someone who quietly upsets expectations while charting her own course. Through her battle with racial identity, her hard-won decisions in love, and her own raw presence with Wash, Tanna provides a rich, emotionally rooted character in the show.
Her story is not ancillary; it's an essential aspect of the show's examination of freedom, belonging, and truth.
