A major character will soon be killed on Dexter.

But star Julie Benz (Rita) makes it sounds (or look, to be specific) as though another shocker is also on the way.

We just have no idea what that will be.

On her Twitter account, Benz posted the following message this week: Shooting season finale.follow @chrisvroman...remember this face. Big reveal in december.

This is the face that accompanies those words. Any idea who it is or what this might mean for the show?
