Justin Walker

Justin is the baby of the Walker clan, an Iraq war veteran newly home and struggling to figure out what comes next. Charming and restless, he drifts between reckless impulse and genuine tenderness, still treated like the family's kid brother even as he carries wounds — visible and otherwise — that nobody quite wants to look at directly.

Dave Annable plays Justin's charisma without letting it soften the character into a simple golden boy; there's real volatility underneath the grin. The show uses him to smuggle in harder material about addiction and war trauma inside a glossy family soap, and Annable sells both the sweetness and the self-sabotage as the same person.
