"The Flash" season 2 could see the death of one of Barry Allen's (Grant Gustin) friends.

On his Instagram account, the former "Glee" star revealed that they already started filming the final episode for season 2.

According to YVR Shoots, one of the photos from the set of "The Flash" season 2 also happened to be at Vancouver's Mountain View Cemetery.

This has led fans to speculate that at least one character will be killed off from the show because why else will Barry and his friends be there too.

"#TheFlash filming season 2 finale in #Vancouver for next week+," the photo caption read.

There are also some speculations that Barry and his friends may also just be in the cemetery to visit a friend and not necessarily because one of them passed away.

Just recently, photos of Barry and "Arrow" lead character Oliver Queen (Stephen Amell) also surfaced online.

The photo revealed that Barry might be present at Laurel Lance's (Katie Cassidy) upcoming funeral. As such, it's also highly possible that the cemetery in Vancouver is the same location for Laurel's funeral.

Meanwhile, the cast members of "The Flash" season 2 were also spotted filming at Cambie Village where Joe West's (Jesse L. Martin) house is.

One of the photos from the set showed Barry talking to his childhood friend Iris West (Candice Patton).

Twitter user @johnnymacjays shared the photo on Twitter and wrote, "Here's a photo from the scene I just watched. #TheFlash."

In other news, details about the upcoming finale episode for "The Flash" season 2 are still being kept under wraps.

However, if the last episode will be as shocking as season one's finale episode, there's really a chance that at least one character will be killed off.

Last season, Iris' fiancé Eddie (Rick Cosnett) was killed off.

"The Flash" season 2 airs Tuesdays at 8 p.m. ET on The CW.

 First day of the season 2 finale for me. With the one and only JLM.
