Arrow: Promise Oliver Queen Made to Laurel Lance Before her Death Finally Revealed

Katie Cassidy as Laurel Lance on 'Arrow'

The promise Laurel Lance made Oliver Queen agree to right before she died has been revealed.

The words, kept under wraps since last season, were unveiled in the Arrow Season 5 preview trailer which debuted at Comic-Con.

While laying in her hospital bed, Laurel (Katie Cassidy) told Oliver, “Your instinct has always been to go it alone.” She added, “Ollie, you can’t.”

Her words are likely the catalyst why, in Season 5, we’ll be seeing Oliver recruiting and training amateur vigilantes. They will attempt to fill the void left by¬†Diggle (David Ramsey), Thea (Willa Holland) — and Laurel — who took some time off from Team Arrow at the end of Season 4.

Arrow Season 5 premieres on Wednesday, Oct. 5 at 8 p.m. on The CW.SuperFable
