ABC

"Grey's Anatomy's" Sara Ramirez and Jessica Capshaw

Arizona's road to recovery following the amputation of her left leg has been a rough one on ABC's Grey's Anatomy, but the process received a jump start when Bailey baited her back to Seattle Grace to help with a case.

With the assistance of a prosthetic, Arizona (Jessica Capshaw) took a giant step forward when she indirectly turned her anger about the loss of her limb toward Bailey and angrily made her way to the hospital, bringing a huge smile to her wife Callie's (Sara Ramirez) face in the process. It was the first major positive sign of her return to form that will continue Thursday when she makes her official return to work.

"Initially, Callie's really trying to not get in the way of Arizona's first day back," Ramirez told The Hollywood Reporter during a visit to the Hollywood set Wednesday.

Callie's support is par for the course this season, which has seen the doc navigate the emotional fallout of a broken promise to Arizona that she would ensure she kept her leg.

"Callie is trying to help from a distance and has some safety nets planted out in case anything goes wrong," Ramirez says. "She's trying to help her wife, but from afar because she doesn't really fully understand what it is her wife needs."

While nobody expects her to be 100 percent back in the saddle immediately -- and in classic Grey's form, not all will be smooth sailing -- Arizona's return will at first feel almost seamless with the peds surgeon also reuniting with Alex, who unbeknownst to Arizona was the one to perform her amputation.
