The season 3 finale of Arrow is going to be pretty intense, according to showrunner Marc Guggenheim.

Will Oliver Slay Ra's al Ghul In Finale?

In an interview dated May 12 with The Hollywood Reporter, Guggenheim revealed that they had never attempted a concluding episode as this one, and it will actually make fans wonder about the future of the CW series. The finale will seem like an end to the show, Guggenheim suggested.

When asked how the finale will lead into the next season, Guggenheim revealed that it leaves no window for a segue or plot continuation.

"It gives you a very definitive end. It does feel like a series finale. At the same time, now that we're working on season four, there are plot threads and notions from the season finale that get pulled into season four. It really does function on both levels, much more so than previous season finales," he said. "We've never ended a season the way we're ending this season, where literally you are going, "How can the show go on?"

Guggenheim went on to explain by using season 1 as an example and how although it featured a dramatic death of a key character it did not put an end to the essence of the show. He hinted that this time around the identity of Arrow will be obliterated in a way.

"At the end of season one in the wake of Tommy's death, there was a question of how can Oliver go on? But there was no question of how the show was going to be the show," he said. "Here, literally there is no more Arrow identity. There is no more lair. Relationships are fractured. All the things that sort of make the show the show are kind of gone. It's an interesting conundrum the finale poses, which is, 'OK, that was a really satisfying ending, but I know there is a season four, so how is there going to be a season four?' It's a cliffhanger."

'My Name is Oliver Queen' will air on May 13 on The CW.
