Stargate Atlantis co-star Rachel Luttrell is headed to Arrow, guest starring in next week’s new episode of the DC Comics superhero show.

Luttrell — Atlantis‘s Teyla Emmagan — will play a character named Rosie, who from the looks of the photo released today by The CW is a tough-as-nails antagonist, part of a demolition team that is set against Oliver Queen and his friends.

Here’s how the network describes the story:

Oliver and team uncover HIVE’s plan to take out Team Arrow once and for all. With HIVE’s next attack imminent, Lance wonders if Donna is safer without him in her life. Meanwhile, with the wedding fast approaching, Oliver begins to feel guilty that he hasn’t told Felicity about his son.

“Code of Silence” is also the second episode of the season directed by James “BamBam” Bamford, who served as Stargate‘s stunt and fight coordinator for many years before joining Arrow — which is now in its fourth season. The show films in Vancouver, British Columbia.

The episode will air on February 17 (8/7c).
