As "Grey's Anatomy" season 10 continues airing, spoilers have surfaced regarding Alex and his Dad, Arizona and Leah, and tonight's episode!

Tonight's episode is called "Map of You," and according to various sources, is based on a medical case in Rochester, New York.

Reportedly, Jamie Arliss was saved when the doctors injected superglue into a tumor in her heart, a procedure which, until then, had never been attempted.

Should be very exciting!

Meanwhile, spoilers confirm that "Grey's Anatomy" season 10 will see the return of Alex's father, and more will be revealed regarding the origin of their feud.

"Since Jo never had a family and she's always longed for one, it's hard for her to understand why Alex would not want to have a chance to know his father," says Shonda Rhimes according to TVLine.

And one new potential couple who has every "Grey's Anatomy" fan talking is Arizona and intern Leah.

"Leah loves to fall in love, so I knew it would be juicy because that's who her character has been established as: She's an easy faller. And I love Jessica. The fans love "Calzona" so much that I was excited to stir it up," says actress Tessa Ferrer to Hollywood Reporter.

"I think Leah is open to anything that comes her way, so yes, she's open to a romantic relationship but we'll have to see if Arizona is with Leah."

"At a certain point, when you're being cast as the villain, then the villain realizes that even though they don't feel very villainous, they're going to at least need some friends and people to relate to on some level. The attention and the possibility make her feel something that's not bad," says Jessica Capshaw to TVGuide.

"It's not like she's running into a relationship and being like, 'Oh, this thing with Callie is over, so I'm going to start this new big thing.' It's just very human. She's felt very bad for quite a while, and this is something that offers her a little relief from that."

So what do you think? Do you want to see Arizona and Leah get together?
