'Arrow': A Familiar Figure Figures Out Moira Queen's Darkest Secret (VIDEO)

'Arrow': Familiar Figure Uncovers Moira Queen's Darkest Secret

While Moira's acquittal on "Arrow" was a surprise big enough to shock her entire family, the show saved its best for last. In just a few moments, the whole season was turned on its head, and the road forward was changed irrevocably. After escaping a certain guilty verdict, Moira was taken to a remote part of the city. There, she was stunned to see Malcolm Merlyn.

"They said you were dead," she said. But Buddy TV's Carla Day wasn't surprised at all. "Since this summer, it was pretty clear that Malcolm didn't die on the roof. The mystery was when would Malcolm return, not if he would return," she said. "With Malcolm back in town, it will be interesting to see how he reacts to whatever Blood is doing. Is it possible that the Dark Archer and Arrow could work together to bring down an enemy of the city? That would be quite intriguing.”

Earlier, Moira had admitted to her children that she had slept with Malcolm many years ago. Malcolm had been following her case closely, and convincing the jury to let her off was only one part of what he was up to. “Imagine my joy at learning that Thea is my daughter," he said. It was clearly the last thing Moira wanted him to discover. That reveal surprised Collider's Dave Trumbore. He was sure the secret was going to be that Malcolm was Oliver's father.

"Arrow" airs Wednesdays at 8 p.m. EST on The CW.
