The original Team Arrow works to protect Black Siren aka Laurel (Katie Cassidy) on the upcoming episode of "Arrow" season 6.

Titled "Collision Course," this week's episode will see the original Team Arrow band together for one big mission. Oliver (Stephen Amell), Diggle (David Ramsey) and Felicity (Emily Bett Rickards) butt heads with Dinah (Juliana Harkavy), Curtis (Echo Kellum) and Rene (Rick Gonzalez) when they discuss their plan on how they should handle Black Siren (Katie Cassidy).  A major fight ensues when the two teams collide.

New photos for the episode have been released, offering more context for the storyline. Although previous photos showed the original Team Arrow with Thea (Willa Holland) seeking refuge in a mansion, latest images from the network hint that they will be joined by both Laurel and Quentin Lance (Paul Blackthorne).

While Quentin wants to give his daughter a chance to redeem herself, Dinah is still hell-bent on killing her. Dina will apparently stop at nothing until she gets justice for the death of her lover Vincent (Johann Urb).

Earlier this month, Cassidy shared a photo of her head inside a plaster mold — the same one used for creating molds of an actor's head for some type of design process. The image has led fans to speculate that Cassidy's "Arrow" character might get a new costume or a new mask in the show. 

Comicbook notes this is not the first time Cassidy was fitted with a similar face mold. Back in season 3, she also had the same thing done just before Earth-1 Laurel entered the show as Black Canary. Given that her previous costume is still being kept in Team Arrow's bunker, it's safe to say that the new mask is for some new costume altogether. 

"Arrow" season 6 airs every Thursday night at 9 p.m. EST on The CW.
