We have seen Rick and Kate get down and dirty this season on Castle, but on Monday’s episode, everything isn’t what it seems.

In Season 5, Episode 10, “Significant Others,” Castle feels bad that Alexis interrupted their alone time, so he says, “I’m going to make this up to you in so many ways.” Bow chicka bow wow. But before he can say any more — or kiss her! — a surprising guest pops in and ruins the moment.

Yep. The deep-fried Twinkie from Rick’s past is back: his ex-wife, Meredith! While we’ve known for months that Scandal’s Darby Stanchfield would be reprising her role (and causing a whole lotta trouble in Caskett land), Entertainment Weekly has the first look at the couple’s first encounter with the fiery redhead.

Check out the clip over at EW, and then share your reaction below!

Original Air Date: Castle Season 5, Episode 10: “Significant Others” airs on Monday, Jan. 7, 2013 at 10 p.m. ET on ABC.
