Even as Felicity finds herself in a darker place in the wake of her boyfriend's death, her family won't be around to offer her comfort. When "Arrow" Season 5 returns from its mid-season break, her father -- aka the Calculator -- won't be there to help, and neither will her mother Donna. However, that doesn't mean they won't be back in the future.

According to executive producer Marc Guggenheim, Donna and the Calculator won't be back because the show is moving in a new direction. “I would definitely love to bring him back, and I would love to bring Charlotte Ross back as Donna, but [we were like], ‘Let’s tell a new story, something we haven’t done before,'” he told TVLine.

Guggenheim also teased that Felicity will a meet a few people in the back half of the season that are connected to her past. “As with all things related to 'Arrow,' it’s not what you initially think it is, and it will ultimately relate to the season’s overall theme of ‘legacy.’ But it will be very specific to Felicity,” he hinted.

Additionally, he explained that Felicity's new, darker direction can't be blamed solely on Billy Malone's death. Rather, her experiences over the course of the show -- including the Havenrock disaster -- will culminate in her new attitude. "Billy was the final straw," he said. "It’s also the sum of the fact that Felicity has been living in this darker world for the last four-plus years now…. How has that affected her way of thinking about things?” He added that this will be directly addressed in Season 5 Episode 11.

In the mid-season finale, Oliver accidentally killed Felicity's boyfriend after Prometheus led him on a goose chase through one of the Hood's old hits. Prometheus dressed Malone up as himself and offered Oliver a target, which Oliver seized; to his horror, he discovered Malone duck taped and gagged under the mask. He returned to the bunker visibly shaken and remorseful, immediately confessing his error to Felicity. Felicity turned around and blamed Prometheus for Malone's death, but this act will send her down a dark path.

Starring Stephen Amell as the Emerald Archer, “Arrow” airs at 8 pm ET/PT on The CW. The series also stars Emily Bett Rickards, David Ramsey, John Barrowman, Willa Holland and more. “Arrow’s” fifth season returns to the CW on January 25.
