As noted by our sister site Deadline, which first broke the news of Dunne’s status change, the character’s growing importance was foreshadowed in the final moments of the Season 3 finale when Nicky was seen (via flash-forward) at

ailing, elderly Rebecca’s bedside. Dunne appeared briefly in Tuesday’s Season 4 premiere when he crossed paths with fellow war vet Cassidy (played by Once Upon a Time‘s Jennifer Morrison).

Dunne’s pre-This Is Us TV work includes stints on Alias, Law & Order: Criminal Intent, Damages, House of Lies and I Love Dick.
