"Arrow" Season 4 could see the death of one of its most-loved characters, Felicity Smoak (Emily Bett Rickards).
According to Design & Trend, "Dark Waters" will be action-packed and will also feature some twists in the lives of Oliver (Stephen Amell) and the other characters.
One of the highlights from the fall finale episode is Damien Darhk crashing Oliver's party. While there, the villainous character will use his psychic powers to manipulate Oliver and then throw him against a glass wall.
Damien will also be terrorizing Oliver's girlfriend, Felicity. It seems that Damien wouldn't be successful at killing Oliver, so he will attempt to get rid of his girlfriend instead.
"The best way to teach someone a lesson isn't to punish them," Damien told Felicity.
Meanwhile, "Dark Waters" will also see Oliver attacking HIVE at the beginning of the episode. Damien will be surprised by Oliver's arrival at HIVE, so he will attack his mayoral holiday party in return.
"Dark Waters" will also see the return of Malcolm Merlyn to Starling City. Malcolm's return will have something to do with his daughter Thea. The official synopsis for the episode reveals that Malcolm will warn Thea about something dangerous.
In other news, "Dark Waters" reportedly most likely guarantees that one character will be killed off from "Arrow" Season 4. However, it seems highly unlikely that the creators of the show will decide to take the life of Felicity when so many things can still happen to the character especially in relation to Oliver.
According to International Business Times, "Arrow" Season 4 previously revealed in its flash forward episode that one of its characters will be killed off.
"Given that Darhk is about to make some kind of horrible and brutal play against the secret hero's very public mayoral campaign, this may be the big moment when the team loses someone vital," the publication noted.
"Arrow" Season 4 airs Wednesdays on The CW.
