The CW's Arrow and The Flash are gearing up for their first major crossover, which will occur in the eighth episode of the shows' third and first seasons, respectively. Fans of Arrow should be happy to know that a significant moment for Oliver Queen occurs during the Flash episode of the crossover.

"It's my idea," star Stephen Amell revealed to IGN about the moment in question. "I can't tell you anything about it other than it relates to Central City. When I saw it in the Flash script, it ended up being really actually quite gratifying. First of all, when I say it was my idea, everyone has ideas all the time. It all goes into a melting pot. I just thought it would be a cool idea. I thought it would be a cool idea for The Flash. It ended up being a cool idea that we were able to utilize me for because we were doing a crossover with The Flash. So it was very professionally gratifying."

Amell went on to describe how the two teams from Starling City and Central City interact and further teased the big moment.

"I just spoke with [director] Glenn Winter on Wednesday. We were shooting some stuff for episode 308, which is our Flash crossover episode, and he said that he had seen a cut and it was his favorite thing that I have been involved in so far on the show. I can't say anything about what it has to do with other than that the crossovers...We are very much guests in Central City and very much the rogue team in Central City. Just as much as Grant [Gustin] and the Flash team are guests here. We talk and we delve into the differences between Central City and Starling City but this particular moment is very much an Arrow-centric moment. "
