Arrow season 2, episode 12 "Tremors" gave its fans a lot of cliffhangers! But, there are lot of spoilers surfacing online that fans will be thrilled about including some details on the "Huntress"!

[WARNING: Arrow season 2 spoilers ahead!]

About 2 weeks ago, Arrow season 2 executive producer Guggenheim talked to TVGuide and revealed some details about Oliver and Felicty love team.

When asked about a romantic potential for the two, Guggenheim said that it's a possibility!

"There's always potential. There's clearly a connection between the two of them and a lot of chemistry between Stephen and Emily. Whether that gets consummated in some way, I would say everyone has to keep watching. Part of the fun for us with the show is doing this razor's edge walk with them. The characters are two very different people, yet they're drawn together."

However, Guggenheim also revealed that the two are basically drawn to other people as well.

"They're also drawn to other people at the same time. A big part of Episode 10 is the fallout from the Barry-Felicity flirtation. They have some quintessential Oliver-Felicity moments in the first four to five episodes of the second half of the season."

Guggenheim already talked about Barry-Felicity tandem. But, Oliver has his own list of women in his world. And, one of the first of these women is Helena Bertinelli, another vigilante in the show named the "Huntress."

Last January 24, Guggenheim teases about two upcoming episodes wherein other DC characters appear.

"There's two episodes in a row, where we're keeping the titles secret, because both episodes will just blow people's minds," the Arrow EP said to NewsRama.

Three days after Guggenheim's statement, TVGuide revealed the title of one of the two episodes Guggenheim mentioned.

According to TVGuide, the title for the episode is "Birds Of Prey," wherein Jessica de Gouw (from Dracula) will come back as the "Huntress." TVGuide also revealed that she'll be back to take revenge, but Arrow and Canary will be there to try to stop her.

"Helena will return to Starling City in hopes of exacting revenge after the Arrow arrests Frank. However, to kill him, she's going to have to go through the Arrow... and Canary (Caity Lotz)," TVGuide reported.

The said episode will air on March 26, Wednesday on The CW.

We all know that the Huntress and Arrow had a "thing" before. Will she cause problems with Oliver and Felicity? We will soon find out!

On the other hand, one of Oliver's love interests, Laurel Lance, is in big trouble! And, it looks like her sister, Sara - The Canary, will be there to help her.

During this week's episode, the last part of the scene takes us by surprise as Sara has finally revealed herself to Laurel.

Two weeks ago, Guggenheim already shared to TVGuide that Laurel will know her sister is alive.

"Laurel's spiral into drug and alcohol abuse will worsen after she learns a dangerous secret. But there's some optimism on the horizon. "Laurel will be learning that her sister is alive," Arrow EP Marc Guggenheim says.

Laurel was pretty much wasted when she saw Sara on this week's episode. How would she react once she's sober?

Arrow season 2 returns next week on The CW!
