The midseason finale of Arrow Season 5 ended up with a resurrection and an unexpected death. The fall finale of the Arrow Season 5 is going show the dark fate of Felicity (played by Emily Bett Rickards).

Prometheus, who is the eternal enemy of Oliver because Oliver killed his father, tricks Oliver into killing Billy by putting his costume and mask on Billy. Prometheus never wants to kill Oliver, rather wants him to be tortured beyond the extent of death. According to Newseveryday, Laurel will make a return on "Arrow" Season 5.

Oliver (Stephen Amell) mistakes Billy for Prometheus. He chases the man and hurls multiple arrows at him, bringing his end. When he removes the mask of the victim, to his utter despair he finds that it is Billy Malone(Tyler Ritter), an SCPD detective and the present beau of his ex-girlfriend Felicity Smoak!

The incident casts a deep shadow over Oliver's soul as he starts believing that he ruins everyone's life around him; he remembers the words of Susan Williams (Carly Pope), as she told him so in the past. Felicity also breaks down at this grim news.

The show is going to return on January 25, after the seven-week hiatus. It will be shown that Felicity does not blame Oliver because she judges the situation in which Oliver was tricked into killing Billy. Her rage is rather directed towards Prometheus, reports Wendy Mericle, the showrunner.

According to TVLine, The utter grief of Malone's death directs Felicity's life in a different way. The computer wizard gets detached from the Arrow team and contemplates some dark actions, which are against common ethics and morality. Mericle adds that this potential was hidden in the character and the story was not there to sketch her character in this shade. He is quite excited about the new story.
