Arrow Recruits True Blood's Rutina Wesley For Mystery Role

True Blood's Rutina Wesley will join Arrow for a multi-episode arc, TheWrap reports.

The as-yet-unspecified role will bring the former Tara Thornton into the fourth season of the CW drama, which is loading up with guest stars as shooting gets underway.

While there's certainly no guarantee, multi-episode arcs and unspecified names often mean she's of significance to the season-long storyline (in this case, a battle with Damien Darhk and H.I.V.E.), and possibly could even get a costume of her own.

Much of Arrow's recent casting activity seems to center on the Oliver Queen side of things, rather than the Green Arrow side, with a lot of political candidates and advisers entering the fray. In the comics, Oliver Queen has often been politically active and at one point was the mayor of Star City. As recently as last season, though, producers said that to write such a storyline in today's television landscape would be incredibly difficult, since giving your lead character well-defined political opinions or even just a party affiliation could alienate half the audience.

Arrow returns on October 7 at 8 p.m. and airs new episodes Wednesdays at 8 p.m. ET/PT on The CW.
