“I think people will be really happy,” showrunner Meg Marinis tells EW of the return.

But when theGrey’swriters came across this particular medical story, they knew they needed to get Capshaw back.
Needless to say, Arizona’s usual dose of sunshine is much needed.
“We’re going to see her with some familiar faces.
Obviously, she’s in the trailer with Bailey [Chandra Wilson] and they have a great relationship.
We’re going to see her come across a challenge.
We’re going to see her laugh.
We’re going to see her be medically awesome.
We’re going to see her teach.
I think people will be really happy.”
Arizona’s big return airs Thursday, April 4, at 8 p.m. ET/PT on ABC.
