One of the many surprises in the lead-up to "Crisis on Infinite Earths" is the inclusion of Audrey Marie Anderson's Lyla Michaels as the DC character Harbinger. According to Arrow star David Ramsey, Diggle and his wife Lyla will soon resolve their issues with her deception.
"[Diggle and Lyla] are going to have it out soon, but it won't be in this episode," Ramsey told TVGuide. "Some of those questions you have for Lyla will be answered in this episode, but they'll be answered between Oliver and Lyla, not between John and Lyla."
The last episode of Arrow, titled “Prochnost," ended with Black Canary revealing Lyla's secret to Oliver and Diggle, only for the trio to be attacked with tranquilizer darts in the episode's final moments. While tonight's "Reset" may not resolve the brewing conflict between Diggle and Lyla, at least we know some questions will be answered.
