'Arrow' Season 2, Episode 14 Spoilers: Black Canary vs Laurel Lance, Felicity vs The Clock King; Best Episodes Teased by Stephen Amell [Watch Promo Video]

"Arrow" Season 2, Episode 14, titled "Time of Death" airs on Feb. 26 on The CW. This supposedly amazing instalment is sandwiched by two exciting episodes. Stephen Amell wouldn't say which among Episodes 13, 14 and 15 is the best. But he has earlier teased on Facebook that these three episodes are truly action-packed.

Spoiler alert: This feature contains spoilers on Arrow Season 2, Episode 14. If you are not up to date, read at your own risk.

Here are some of the spoilers on Arrow 2x14: Felicity goes against the Clock King. Black Canary (Caity Lotz) remains at odds with sister Laurel Lance. Deathstroke launches assault against Moira Queen (Susanna Thompson).

Robert Knepper ("Prison Break," "Mob City") guest stars as William Tockman, aka the Clock King in Arrow 2x14. He is "absolutely astounding," in Time of Death, according to showrunner Marc Guggenheim. Incidentally, Knepper "will play President Snow's minister Antonius in The Hunger Games: Mockingjay - Parts 1 & 2," reported Deadline.com.

The CW has a producer's preview video on Arrow Season 2, Episode 14. Watch it below or go to this YouTube page.

The Clock King aside, "Time of Death" deals with Felicity's (Emily Bett Rickards) thoughts and feelings about Sara Lance. She is now a resident in The Arrow lair and officially involved (again) with Oliver Queen (Stephen Amell). Felicity is feeling insecure, and words must be said. Felicity Smoak does not usually hold her tongue, so Olicity must watch this "Felicity-centric episode."

The second central character of Arrow 2x14 is Sara Lance. Freed by Nyssa al Ghul (Katrina Law), Sara has now come home to Starling City. She is having a welcome-home-we-thought-you-were-dead party. (Update: Spoilers revealed Nyssa is definitely coming back to the show for more action. Felicity Smoak and Nyssa are only two of the DC Comics characters that have expanded a great deal since appearing on The CW's Arrow. Many viewers were surprised how the TV version developed Sara's relationship with Nyssa.)

Caity Lotz has spoken to TVLine.com about Sara and Laurel, as well as the feud between the Lance sisters. Arrow fans expect Laurel to be the Black Canary eventually, but the series is showing a brilliant journey as to how this happens.

"It's not like Laurel's on a strong foundation as this is coming in. But Laurel's got a cool journey ahead, for sure," Lotz said.

Meanwhile, Manu Bennett's Deathstroke (formerly known as Slade Wilson on the island) is out to stop Moira Queen from running for Starling City mayor post. Some fans are thinking Oliver Queen would find out what he's up to and their "war" would last up to the Arrow Season 2 finale. (Update: Spoilers indicate this is actually happening.)

"We knew that John Barrowman's character [of Malcolm Merlyn] would be the Big Bad of Season 1. And we knew that if Manu [Bennett] worked out, in success he would be the Big Bad of Season 2," Guggenheim told TVLine's Matt Webb Mitovich, who visited the Arrow set.

Arrow Season 2, Episode 14 is followed by "The Promise" airing on The CW on March 5. Stephen Amell said he is very proud of Arrow 2x15. "[It's one of] the episodes that take our show to another level," the actor told TVLine.
