Tia is a supporting character in Apple TV+’s dramedy Shrinking, portrayed by actress Mia Setton. Within the show, Tia is the sister of therapist Janet (played by Christoph Waltz) and serves as a grounding, relational anchor who complicates Janet’s controlled worldview. This evergreen profile explains who Tia is, how the series presents her, her central relationships, and how she fits into the show’s broader themes and narrative structure.
Tia’s Role and Character Overview
Tia exists primarily through her familial ties, especially with Janet and their father. Unlike Janet, who adopts an emotionally distant, clinical approach to therapy and life, Tia embodies a more expressive, pragmatic perspective. Her presence highlights the generational and temperamental contrasts within the family and offers viewers a lens into how Janet’s behavior ripples outward to those closest to him.

As Janet’s sister, Tia functions as a foil and a counterbalance. Her interactions with Janet reveal underlying tensions around care, responsibility, and emotional expression. Tia’s pragmatic outlook often clashes with Janet’s methodical, almost experimental approach to therapy, making their exchanges a vehicle for exploring themes of control versus empathy.

Thematic Significance of Tia
Tia’s presence consistently brings the show’s themes into domestic focus.
