Prometheus Makes His Move in Arrow's "What We Leave Behind" Synopsis

The hits just keep on coming for Oliver Queen and company.

Just a week after Team Arrow battles aliens from the Dominion Homeworld, they're faced with a crazed assassin trying to take them out at home.

The CW has released the official synopsis for "What We Leave Behind," December 7's episode of Arrow, in which Prometheus goes after Curtis, leading Oliver to believe that the villain knows who the members of Team Arrow are and how to get to them.

"You're definitely not happy to see your husband come home with bruises and scrapes every week," said actor Echo Kellum when asked about how Curtis's personal life might be impacted by his work with Team Arrow. "I think he's going to have a little bit of trepidation about what Curtis is getting into -- but it's the kind of thing where every relationship has to worry. Even if you're going away working on tech or power lines. It doesn't matter; when you're away from the person who loves you, it's going to cause stress."

One big question, of course, will be how Prometheus knows this, and what it means (if anything) that Quentin Lance is off the board for the time being.

You can check out the official synopsis below.

PROMETHEUS MAKES A DEADLY MOVE AGAINST OLIVER AND THE TEAM — After Prometheus attacks Curtis (Echo Kellum), Oliver (Stephen Amell) realizes Prometheus knows all of Team Arrow's secret identities and is planning to come for them one by one. Felicity (Emily Bett Rickards) and Detective Malone (guest star Tyler Ritter) discover a clue that links Prometheus to Oliver's past.

Antonio Negret directed the episode written by Wendy Mericle & Beth Schwartz.

Arrow airs on Wednesday nights at 8 p.m. ET/PT on The CW. "What We Leave Behind" will debut on December 7, 2016.
