TVLine got news of the nature of crossover episode from Stephen Amell, who plays Oliver Queen aka the Arrow, on the show. Amell didn't give much away but definitely amed up the hype for the episode. "I can't tell you anything about it other than it relates to Central City - and when I saw it in the Flash script, it ended up being actually quite gratifying," he said. "[Director of photography] Glen Winter said it was his favorite thing I've been involved in so far on the show."

In other news about the Arrow, Nyssa al Ghul (Katrina Law) is going to confront Oliver about Sara's death in the next episode.

Another highlight of the episode will be the return of Thea (Willa Holland), who finallt returns home.

But one of the most intriguing points of the episode, which will play out to Oliver's disadvantage will be Nyssa telling her father Ra's al-Ghul about Oliver. It has been established that Ra's al-Ghul will be the prime antagonist in this chapter of the CW show. So Nyssa giving Ra's any information about Oliver could be devastating for him.

Nyssa will also be making amends with Laurel (Katie Cassidy) in this episode.

The Magician will air on October 29 on the CW.
