One of Rosewood's more infamous couples, Ezra Fitz (Ian Harding) and Aria Montgomery (Lucy Hale) will hit a little turmoil as the later prepares to graduate. The Christmas episode and its Santa boxer shenanigans will "were "probably the last time you'll see them in a really good spot for a while," Hale confided to Yahoo!.
