The CW’s hit superhero series Arrow has been renewed for a season 3, it will launch a spinoff in the form of The Flash, and its ongoing popularity and ever-stylish handling of a small screen comic book-based universe is proof that the medium really can sustain the long-term, episodic nature of the source material.

So far, season 2 has extended the rogues’ gallery of enemies Oliver Queen (Stephen Amell) is up against, from the League of Assassins to the Suicide Squad, the latter of which will include Bronze Tiger (Michael Jai White)Shrapnel (Sean Maher), Amanda Waller (Cynthia Addai-Robinson), and Deadshot (Michael Rowe).

The upcoming episode ‘Time of Death’ adds another classic villain to the fold: William Tockman, A.K.A. the Clock King, played by Robert Knepper (The Hunger Games: Mockingjay – Part 1). In the above Producer’s Review clip, Arrow executive producer Marc Guggenheim explains how the arrival of the Clock King adds to the disequilibrium Felicity Smoak (Emily Bett Rickards) has been experiencing ever since Sara Lance returned from the dead and was revealed to be the vigilante Black Canary.

And here is a clip from the episode, where Felicity’s ability to back Oliver up in the field is directly challenged:

The Clock King seemed like an odd choice for Arrow, despite the show’s ongoing status as a repository for any and all DC villains, from Count Vertigo to Nyssa al Ghul. The Clock King is perhaps best known for his various appearances as a Batman villain – he showed up during the Adam West era on the ’60s show as well as on Batman: The Animated Series, but he went up against the Green Arrow early on and wound up joining the Injustice League and the Suicide Squad in the comics.

The New 52 version of the Clock King sees him showing up in Gotham City under the influence of Venom and battling the Birds of Prey. His Arrow incarnation once again finds Tockman obsessed with timing, and as we see in the clip above, may prove to be a nemesis for Felicity and only compounds her insecurity in the wake of Sara Lance’s acceptance into the Arrow lair.

There are always some serious threats lurking in Starling City, but Oliver has a potentially massive shake-up on the horizon – will our hooded vigilante need rescuing from the League of Assassins, necessitating “one of the biggest fights in television history?”

If so, he’ll likely need Felicity’s help more than ever, which means that Felicity will have to fight her sense of insecurity and take her place as one of the Arrow’s most trusted and valuable allies.

Arrow returns to the CW on Wednesday, February 26 @8pm with ‘Time of Death.’
