Duncan Kane

Duncan Kane is Neptune High royalty — heir to the Kane Software fortune, former boyfriend of Veronica Mars, and brother to Lilly, whose murder haunts the whole town. He drifts through school looking blank and distracted, dating sweet new girl Meg Manning while seeming only half-present in his own life.

Teddy Dunn plays him as a held breath: pleasant, remote, faintly wrong in a way the show never rushes to explain. That stillness turns him into a walking question mark inside Veronica's investigation — the ex who should be an open book but reads instead like someone guarding something, even from himself.
