Royal Pains fans, you are cordially invited to a very special two-hour episode of this USA Network hit.

Airing in December, the installment will be based around Evan and Paige's wedding, while also featuring the return of Jill Flint as Jill Casey.

Look for a few flashbacks to the Lawson siblings' lives before they moved to the Hamptons, including an appearance by Emma Caulfield as Hank's ex, and for a snowstorm to be bearing down on Evan's big day.
