The 4th season of Arrow premiered on October 7 and has already left us speechless. With big fights between Oliver and the rest of Team Arrow and the reveal of one of the bigggest betrayals we've seen in this show so far – Captain Lance (Paul Blackthorne) is, in fact, working with Damien Darhk (Neal McDonough), the leadear of the H.I.V.E. – we are sure you can`t wait to find out what`s going to happen next in the show. Luckily, we are here to save you!

First, we need to address the last scene of the premiere. Yes, the one that shows Oliver (Stephen Amell) standing over a grave, promising to kill ˜him˜. But who is it? According to Marc Guggenheim and Wendy Mericle, the executive producers of the show, neither they know this answer – but one thing they can guarantee is that, whomever it is, it`s really dead.

˜It’s not a fake-out”, said Guggenheim to Entertainment Weekly.

Olicity's love story

Another thing fans are crazy to know is the relationship between Oliver and Felicity (Emily Bett Rickards ) and how it will develop from the season 3 finale, where they rode off into the sunset. From all we know, the show`s going to treat them as “co-workers who started dating,” and we are going to watch both their personal and professional relationship grow – and yes, this includes scenes of more domestic and intimate moments.

But, as nothing is only happiness in Arrow, we also found out Elysia Rotaru was cast as a love interest for Oliver this season. Luckily for the olicity fans, she`s going to appear only in flashbacks. In the words of Marc Guggenheim, “Oliver is going to have a love interest in the past that will serve as a parallel or potentially a contrast to his love affair with Felicity in the present."

New villains are coming!

This season we are also meeting two iconic characters from DC: super villain Anarky (Alexander Calvert) will make an exception fighting against Batman and will team up with Darhk this year; and super-genius Mister Terrific (Echo Kellum) will be working as a tech whiz for Palmer Technologies.
