"The Flash" season 2 will see Laurel Lance (Katie Cassidy) or the Black Canary in an episode with lead character Barry Allen (Grant Gustin).
Just recently, a video from the set of the hit The CW series was leaked online. It showed Laurel and Barry coming face-to-face on Earth-2.
By the looks of it, Black Canary and The Flash are not good friends in the alternate universe.
A longer video from the set of "The Flash" season 2 was also leaked online on March 31.
It showed production staff fixing Cassidy's hair before the cameras started rolling. The video lasted for almost three minutes
Photos from the set of the episode were also posted on Twitter. One of the photos showed Black Carry and The Flash together.
Other photos were simply of Cassidy wearing her costume as the Black Canary.
It was also revealed that the episode was shot in Vancouver.
Meanwhile, it is still unclear when Cassidy will appear on "The Flash" this season. What is only known is that the cast members are currently filming episode 22.
With this, it's possible that Black Canary will crossover to Central City from Starling City on the same episode.
In other news, it has already been confirmed that Laurel will be killed off from "Arrow" season 4.
At the beginning of the season, Oliver Queen (Stephen Amell) was featured in the cemetery.
During that time, fans started speculating that Oliver's girlfriend Felicity Smoak (Emily Bett Rickards) will be the one to be killed off.
However, it was recently confirmed that Felicity is doing well.
To add to the speculations, photos of Mr. and Mrs. Lance at the cemetery were also leaked online.
The photos somewhat gave fans an idea that Laurel is the one in the grave.
"The Flash" season 2 airs Tuesdays at 8 p.m. ET on The CW. The series is currently on a short hiatus.
