Arrow is signing off with the help of a couple of familiar faces: Colin Donnell and Josh Segarra are returning to guest-star in the CW drama's upcoming eighth and final season, Entertainment Weekly reports.
Donnell, who's wrapping up a four-year run on Chicago Med, played Oliver's best friend Tommy Merlyn in Arrow's first season, while Segarra played Adrian Chase, also known as the serial killer Prometheus, in Season 5. Both actors have returned to the show since their characters' deaths.
As expected, it sounds like there will be a twist with each of their returns this time around, too. Executive producer Marc Guggenheim told EW that Donnell is "not coming back as the Tommy we know," while showrunner Beth Schwartz revealed that Chase "comes back in a different way than expected."
In the multiverse, anything's possible.
Arrow returns Oct. 15 at 9/8c on The CW.
