Isaac Henderson

Isaac drifts through the Truham friendship group with a book permanently in hand, more comfortable observing than talking. He listens more than he speaks, watching his friends' dramas unfold with quiet amusement, and seems oddly unbothered by the romantic pairings-off happening around him. He's steady, bookish company, easy to overlook and easy to underestimate.

Tobie Donovan plays Isaac almost entirely through stillness — a raised eyebrow, a page turned at just the right moment — making him the group's dry Greek chorus. The writing uses his quiet detachment from romance as a gentle, unforced question rather than a punchline, letting viewers sit with him instead of rushing to explain him.
