The next episode of Arrow will likely provide more detail on a villain who could put Felicity's life in danger.

Oliver To Push Everyone Away on Arrow?

On Thursday, the official synopsis revealed what will happen on the next episode called Time of Death, which will air on Wednesday, Feb. 26.

With Sara's return, more of the characters' lives will be impacted and she will likely have a longer appearance, according to the synopsis.

Nyssa's Motive Leading To Harm?

"Oliver (Stephen Amell) brings Sara (Caity Lotz) into the arrow team," the synopsis read. "Watching Oliver and Diggle (David Ramsey) spar with Sara and talk old scars, Felicity (Emily Bett Rickards) starts to feel left out."

The villain making his way around is named William Tockman a.k.a. The Clock King. He is a thief with the ability to open any of the bank vaults in Starling City, who will also have an effect on Felicity.

"After the Clock King infiltrates the computer systems in the lair, Felicity feels pressure to prove her worth," the synopsis continued. "When she gets a lead on Tockman's whereabouts, she heads out without the team, putting her in peril."

It also looks like there will be some intense drama with Laurel when she sees Oliver and Sara together.

"After Lance (Paul Blackthorne) makes his case for a family dinner, Laurel acquiesces, but when Oliver shows up with Sara, she loses her temper on both of them."

Arrow airs Wednesdays at 8 p.m. on The CW.
