Callie (Sara Ramirez) might not be so hot on Leah (Tessa Ferrer) these days on Grey's Anatomy, but she is forging a new friendship with another one of the second-year residents!

Camilla Luddington tells TV Guide that her on-screen alter-ego, Jo Wilson, will find a new buddy and mentor in Callie this season — when she joins the good doctor in the orthopedic track.

"She bonds with Callie," Camilla says. "They both have a temper, and in a strange way, ortho — because it's very physical and you're breaking bones — helps vent that for both of them."

So Jo's taking out her anger on bones now? The vending machines of Grey Sloan Memorial just breathed a heavy sigh of relief.

Meanwhile, Jo is the second gal pal with whom Callie has gotten closer this season — after she bonded with Meredith (Ellen Pompeo), moved in with her and Derek (Patrick Dempsey), and even accidentally kissed Mer as she left the house one morning.

Hopefully Callie's surgical work with Jo goes better now than it did in the past — the last time we saw them scrub in together, the operation resulted in a malpractice suit.

But on a lighter note, now that we have Jo joining Callie in ortho and Alex rocking peds with Arizona, we sense some cute double dates in their future!
