Olivia's age is one of those details that feels intentionally ambiguous. The show plays with the idea of adulthood versus adolescence, and her character embodies that tension. From what I gathered, she's written as 18—right on that cusp—but her backstory suggests she might be slightly older, maybe 19 or 20. The ambiguity works because the series isn't about numbers; it's about the messy transition into independence. Olivia's struggles with identity, relationships, and societal expectations hit harder because of that deliberate vagueness. It’s like the writers wanted us to focus less on her age and more on how she navigates the chaos of growing up.
That said, fans have debated this forever. Some episodes hint at her being a high school senior (so 17–18), while others imply she’s already in community college. The show’s timeline isn’t linear, which adds to the confusion. Personally, I think she’s 18 by the midpoint of the series, but her age feels secondary to her arc—watching her make mistakes and learn from them is what sticks with me.
