TV Line is reporting that Summer Glau (Firefly/ Serenity/ Sarah Connor Chronicles/ Knights of Badassdom)has been cast in the recurring role of Isabel Rochev for season two of the CW’s Arrow.

The character will be set up as one of if not the main adversaries for Oliver Queen in season two of the show.

According to TV Line, here’s the basic gist of what we can we can expect from the character:

“the beautiful and dangerous Vice President of Acquisitions for Stellmoor International, a company looking to take over Queen Consolidated. Per DC lore, Isabel fancies herself a bit of a rightful heir to the Queen family business, and as such she will be eager to get Ollie out of her way.”

Last season, the character was referenced as one of the names on “the list.”
