April (Sarah Drew) and Jackson (Jesse Williams) may have finally consummated their attraction and eloped in the episode of Grey's Anatomy that aired last night, February 27 — Season 10, Episode 13: "Take It Back" — but they won't be honeymooning for long!

As Sarah tells TVLine, the two newly-minted spouses will find out what happens when you secretly marry your best friend after calling off another wedding — without even dating first.

"A lot of it is drama," she explains. "They have to decide to reveal that they're married. And as they are moving forward in this totally fast marriage thing, they realize there are things about each other that they never knew. There are some pretty big issues that they never talked about. For instance, how are their potential children going to be raised? These are things that most [married couples] have already talked about. They're best friends, but they've never actually dated. They had a sexual relationship that lasted a little bit of time, but they weren't even really dating! [Laughs] Things are going to come up that are going to point out some pretty fundamental differences between the two of them.

But it's not all bad news. Sarah tells Entertainment Weekly that we'll still see proof that Jackson and April know each other better than anyone else does: "We get to see some adorable, sweet moments about the ways in which they are who they are and they love each other for being exactly who they are."

Well, the Shondaland logo isn't wrong: Love certainly is a roller coaster!
