Mary (Samantha Smith) will be reunited with her boys as they attend the funeral of a close friend. Meanwhile, the Winchesters will also be meeting a new hunter named Alicia, played by "Pretty Little Liars" alum Kara Royster.

In the upcoming sixth episode of "Supernatural" season 12 — titled "Celebrating the Life of Asa Fox" — Mary will be reunited with Sam (Jared Padalecki) and Dean (Jensen Ackles) as the Winchesters show up at the funeral of one of their closest hunter friends. They will soon find out that a force has been targeting hunters, and the trio of Winchesters will work together to hunt down this evil.

According to the synopsis released by The Futon Critic, "When hunters gather together to celebrate the life and tragic death of one of their own, Sam, Dean, and Mary must take action when a demon starts picking off hunters one by one."

Previously in "Supernatural" season 12, Mary decided to leave the hunter life behind after realizing that she needs time to accept the world that she was resurrected in- one where John (Jeffrey Dean Morgan) is dead and her two boys put their lives in danger every day as hunters.

Will Mary rejoin her two boys after facing this demonic threat going after hunters?

The funeral is being held for their co-hunter Asa Fox, who was portrayed by Shaine Jones. The Winchesters will also be reunited with other hunters, as seen from the episode photos from TV Fanatic.

Sheriff Jody Mills (Kim Rhodes) will be among the gathered hunters at the funeral, while Billie (Lisa Berry) the reaper will be attending to collect Fox's soul. But given Dean's history with Billie, it might be helpful for the former to stay one step ahead of the reaper's other intentions while visiting Fox's funeral.

Meanwhile, the Winchesters will also cross paths with a hunter named Alicia while they hunt the malevolent force taking hunters down. Alicia and her brother were raised by a witch, and now the two also hunt the things that go bump in the night, according to Variety.

"Supernatural" season 12 airs every Thursday at 9 p.m. EST on The CW.
