The fourth season of "Arrow" is coming very soon and speculations abound about the return of Oliver and Felicity to the team.
It has been five months since Felicity decided to give up crime busting and try to live a normal life with Oliver. But some things in their past will not just stay back and will haunt them as they lead a life of what is supposed to be bliss. According to The Christian Post, the couple will be back in season four of "Arrow" after Damien Darhk causes too much trouble. Darhk is proving to be tougher to beat compared with Deathstroke and Ra's al Ghul as he has magical powers and he is in cahoots with H.I.V.E. He also loves to see his victims suffer which is why team "Arrow" is hard-pressed to stop him at all costs.
In the same preview by The Christian Post, the trio of Thea, Diggle, and Laurel will encounter difficulties maintaining peace and order in the city which Oliver is made aware of when he visits his old crew. He thinks about going back but he also gives thought about Felicity and their plans to settle down for good. Rumors are circulating about a possible marriage proposal which will surely spell the end for the couple's crime fighting days.
Oliver betrayed Diggle in season three and the new season will surely be about Diggle trying to make Oliver pay for what he did. Fans are expecting the feud to last a while, even the whole of season four, but that is purely speculation at this point.
Meanwhile, according to TV Line, rumors of flashback episodes for Diggle is just that as of the moment - rumors. Executive producer Marc Guggenheim explains that the show has a history of pulling off successful flashback episodes that oftentimes they derail the main storyline. He said should there be a flashback episode for season four, it will not happen until episode eight.
