In a recent interview with TVLine, showrunner Marc Guggenheim spoke about what fans can expect from the upcoming episodes after Oliver's move to the dark side.

'Evil Oliver' Is 'Going Out Fighting' In Finale, Stephen Amell Teases

In the latest episode Oliver Queen (Stephen Amell) is forced to join the League of Assassins so as to be able to save Thea's life by allowing her access to the Lazarus pit. Fans are now left wondering how things will move forward after this fateful twist in which Oliver has taken on a villainous role.

First off, Guggenheim reveales that this would obviously be a very tough time for team Arrow in Starling City to know that Oliver is playing for the anatgonistic side now.

"The character journey of [Episode] 321 is how the hell Team Arrow moves forward without Oliver," Guggenheim said. He also added that "knowing that he's out there and alive, but a member of the League of Assassins, that's a whole lot harder."

Although each member of the team will deal with this on a personal level as well, and struggle to come to terms with Oliver's departure, this will also form a stronger bond among them, Guggenheim revealed.

"There is a real trinity formed between Laurel, Diggle and Felicity," he said. "They're all leaning on each other. They're processing things in different ways. Laurel is throwing herself into her work saving the city. Felicity is struggling with heartbreak and grief. She really goes through the seven stages of grief with Oliver. And Diggle, something happens in [Episode] 21 that really upends Diggle's world, certainly vis-à-vis Oliver. That's something that will have repercussions for the remainder of the season."

The next episode will air on April 29 on The CW.
