In last week's Grey's Anatomy season premiere, Callie (Sara Ramirez) responded to Arizona's (Jessica Capshaw) cheating heart by leaving their apartment — and taking the baby with her. And now that she and Sofia have taken up residence in the Shepherd dream house, it's starting to feel a bit like Meredith's (Ellen Pompeo) old house (i.e. the revolving door of surgeon tenants) all over again.

And their new living arrangements promise some humor in the midst of all the sad Calzona breakup drama. It "makes for some fun scenes that we got to shoot," Sara told TV Guide. "There's some comedy in there, but [she won't be there] very long."

So can we expect to see some roomie bonding between moms Meredith and Callie? It's totally possible.

"I think that because of all the life changes that they've all experienced … they have more things in common than they used to, specifically Meredith and Callie, now they're both mothers," Sara said. "There is a moment when Callie confided in Meredith early on and it's a moment that surprised me because I don't see a lot of that with Callie and Meredith, but it made sense."

We can't wait to see a friendship bloom between Mer and Callie, especially since they didn't get off on the right foot in the beginning. Remember Callie O'Malley (R.I.P. George)? And when Mer thought that Callie peed without washing her hands?

Plus, with Cristina (Sandra Oh) making her departure by season's end, Meredith may need a new BFF by her side.

Do you think Meredith and Callie will be good for each other, or will Callie overstay her welcome? Sound off below!
