Arrow Cast & EP Preview 'Olicity' Road Trip, Premiere's Shocking Ending

Put it in your calendars now, Arrow fans: By 8:59/7:59c on Oct. 7, your world will be completely rocked.

The CW series’ Season 4 premiere is “one of those episodes where, [when] watching, you’re gonna go, ‘What?!?!” star John Barrowman told Michael Ausiello when the show’s case stopped at TVLine’s Comic-Con interview suite at the Hard Rock Hotel.

“Especially the last scene,” Paul Blackthorne chimed in. “That last scene is gonna haunt the rest of the season.”

Blackthorne, Barrowman, castmates Stephen Amell, Katie Cassidy, Willa Holland, David Ramsey and Emily Bett Rickards — as well as executive producer Wendy Mericle — also excitedly previewed the arrival of Neal McDonough’s Damien Darhk (which TVLine broke earlier that day).

Unlike the villains of seasons past, “Damien doesn’t have any code. He’s just pure evil,” Mericle said.

Also up for discussion: The Olicity road trip (and whether we’ll see any of it when the series returns), what Malcolm’s tenure as the League of Assassins’ head bad guy will look like and what Amell finds “gratifying” about shows such as The FlashMarvel’s Agents of S.H.I.E.L.D.Gotham and the like.

Press PLAY to watch it all unfold.
