In the latest "Arrow" photo, Felicity -- now known as Overwatch -- stands front and center with a T-Sphere in hand. Though she was paralyzed in an attack from Damien Darhk, she recently regained her ability to walk thanks to Curtis Holt's latest technological advancement.
T-Spheres are spherical electronic accessories traditionally used by Mr. Terrific. As fans of the show know, Holt -- who assumes the Mr. Terrific moniker in the comics -- is in Felicity's employ at Palmer Tech and has helped out Team Arrow on several occasions now. The photo may indicate his increased presence on the team, or perhaps more development on the T-Sphere front; T-Spheres have appeared throughout his work station at Palmer Tech, after all.
The photo originally appeared on the show's official Facebook page and announces that the latest episodes of "Arrow" are free, no login required.
