‘Arrow’ season 4, episode 18 preview: ‘Who’s in the grave?’ mystery ends in ‘Eleven-Fifty-Nine’

For the first time since really the beginning of the season, the schedules for “Arrow” and “The Flash” are going to be going separate ways on The CW next week. When it comes to the former show, you’re going to get a new episode next week; meanwhile, for the “The Flash” you’re now left waiting until April 19. (The downside here is that after next week, “Arrow” will be on hiatus until April 27.)

“Eleven-Fifty-Nine” is the title for the next installment of the Stephen Amell series, and based on the synopsis below, they’ve got a major crisis coming up in terms of what Oliver and Diggle are planning to do to Malcolm Merlyn. Take a look at the attached synopsis for some insight on that:

“Oliver (Stephen Amell) and Diggle (David Ramsey) learn that Merlyn (John Barrowman) is going to try to break Darhk (guest star Neal McDonough) out of prison. Meanwhile, Laurel (Katie Cassidy) gets a surprising offer and Felicity (Emily Bett Rickards) has a heart-to-heart talk with Curtis (guest star Echo Kellum).”

Our early assumption based on timing alone is that this is going to a huge episode of the show that really starts to shake things up, and we’ll have more scoop after we see a promo for the next installment. Update: Well, we know for certain that this episode is going to carry directly into the mystery as to who is in that grave.
