'Grey's Anatomy' Season 11 [SPOILERS]: Meredith's Major Secret With Half-Sister, Stars Talk TGIT & Much-Anticipated Return

The long wait for new Grey's Anatomy episodes is almost over. Fans might have waited for weeks to see Meredith (Ellen Pompeo), Derek (Patrick Dempsey), Callie (Sara Ramirez), and the rest of the Seattle Grace gang come back to their TV screens, and while we have gotten through most of the wait, we still have a little more than 48 hours to struggle through. However, to get you through the last hurtle, we do have some spoilers to hold you over until TGIT makes its highly anticipated return to ABC.

E! News sat down with the newest star of the Thursday night hit, Kelly McCreary who plays Maggie on the series, to get the scoop on her relationship with Meredith. She revealed that when the medical drama returns that the half-sister's squabbling is definitely a thing of the past.

"In this Thursday night's episode, you're going to see Meredith and Maggie have a really nice bonding moment," the actress told the news site. "We started off not getting off to a great start in the beginning, these two ladies, and now they're coming along and opening up to each other and sharing really nice moment, sharing friends and sharing secrets. So it's good."

While we aren't sure what "secrets" McCreary is referring too, stars Jessica Capshaw and Camilla Luddington spoke to TV Line also hinting that they have some information that they aren't a liberty to disclose. However, they do say that when the new episode premieres on Thursday that fans will need some "wine and tissues."

"There's such huge stuff coming!" Capshaw told the site. "And it's so top-secret we can't even tell you who is involved.

Luddington echoed those sentiments revealing, "at the table read, people were crying... There's no relaxing. There's no calm before the storm, It's just storm. All storm, all the time."

Grey's Anatomy returns on Thursday at 8 p.m. on ABC.
