Nick Pearson

Nick lives alone in a cluttered house, keeping the world at arm's length with silence, drink, and a shotgun kept close. When Kevin comes looking for answers about Jack's past, Nick is wary, gruff, and reluctant to let anyone back into a life he has spent decades sealing off.

Griffin Dunne plays Nick as a man worn down to essentials—flinching, guarded, allergic to sentiment—which makes every crack in that reserve land hard. The show trusts silence and small gestures over exposition, and Dunne fills the quiet with a lifetime of unspoken weight without ever tipping into melodrama.
