'Arrow' Actor Talks About That Shocking Episode

— -- Spoilers ahead, this is your last warning.

On last night's episode of "Arrow," fans finally found out who was in the grave that's been teased all year.

We had seen Stephen Amell's Oliver mourning someone all season, but only gotten a glimpse of the back of the grave. (I'm stalling a little here.)

Well, last night, DC fans learned that it was Katie Cassidy's Laurel Lance aka Black Canary who died at the hands of Damien Darhk. Lance's sister, the White Canary, died in a previous season, so the showrunners really like killing off Detective Lance's daughters.

Cassidy spoke to Entertainment Weekly about the shocking death, saying "it made sense to me."

"Laurel’s story has come to an end in the 'Arrow'-verse," she said, alluding to the fact that she may appear in other CW series like "The Flash." Also, characters killed off in this series have been known not to stay dead, so there's that too. The White Canary is alive in another series, "Legends of Tomorrow."

Cassidy also explained how her death scene was actually shot twice.

"We had to do a reshoot actually of when I actually die, when Darhk stabs the Black Canary,” she said. “That was a week after. That was the very last scene that we shot. It was so weird because I remember we had broken for lunch, we came back and I was running to set and I was putting on my jacket and gloves and they were just calling me to set to show-wrap me. I didn’t know that I was done. It was a bit of a shock. But it was good. I feel like there was no other way that I would want it to go.”

The loss of the character is something the 29-year-old actress is still dealing with.

"Being there for four and a half years, they’ve become family. It’s hard to not go into work every day and get to work with such amazing people. That part is certainly sad. Again, I was okay with it. We all came to an understanding that this was what was going to happen. I think the shock value is good," she added.
