"Arrow" season 4, episode 19 is rumored to see Diggle (David Ramsey) taking his own life.
In "Canary Cry," Oliver Queen (Stephen Amell) will lead the members of Team Arrow at Laurel Lance's (Katie Cassidy) funeral.
The previous episode revealed that Laurel or the Black Canary was killed by Damien Darhk (Neal McDonough) after Andy turned his back on his brother Diggle all over again.
At first, Diggle did not believe Oliver when the latter warned him that Andy is not really working with them but with the villainous character Darhk.
On Wednesday night's episode, Diggle will continue to be haunted by Laurel's death. A part of him will blame himself for her passing.
There are some rumors that Diggle will distance himself from Team Arrow. Some viewers also believe that Diggle will take the life of some villainous characters even without Oliver's go signal.
These dangerous moves could risk the male character's life. However, it seems that there will be no new deaths on The CW series for now.
Meanwhile, "Arrow" season 4, episode 19 will also see Felicity Smoak's (Emily Bett Rickards) return to Team Arrow.
In the previous episode, Felicity decided to turn her back on the team after she had some issues with her then-fiance Oliver.
Felicity wasn't all too pleased with the fact that Oliver didn't tell her that he has a son.
Following Laurel's death, Felicity will decide to rejoin the team in order to somewhat fill her place.
There are ongoing rumors that Felicity will be trained to become a hero in her own right just like how Thea Queen (Willa Holland) was trained by her father Malcolm Merlyn (John Barrowman).
In other news, executive producer Marc Guggenheim also hinted on the possibility of Felicity and Oliver getting back together.
As of late, this storyline hasn't been written yet, but there's a huge possibility that the two characters will still end up together sometime in the near future.
"Arrow" season 4 is currently on a short hiatus. The series will return to The CW on April 27 at 8 p.m. ET.
