The CW has revealed the first promo images for episode 2.14 of "Arrow" which you can check out in the gallery viewer below. Titled "Time of Death," the episode is described as follows:

"Oliver brings Sara into the Arrow team. Watching Oliver and Diggle spar with Sara and talk old scars, Felicity starts to feel left out. The team is investigating a villain named William Tockman, a.k.a. The Clock King (guest star Robert Knepper), who is a brilliant thief armed with technology that can open any bank vault in Starling City. After The Clock King infiltrates the computer systems in the lair, Felicity feels pressure to prove her worth. When she gets a lead on Tockman’s whereabouts, she heads out without the team, putting her in peril. Meanwhile, Oliver throws Sara a welcome home party, but Laurel refuses to attend. After Lance makes his case for a family dinner, Laurel acquiesces, but when Oliver shows up with Sara, she loses her temper on both of them."

Directed by Nick Copus​ and written by Wendy Mericle & Beth Schwartz, "Time of Death" will air February 26. "Arrow" airs on Wednesdays at 8 P.M. ET/PT on The CW.​​
