Here's the official trailer for the new season of Homeland. Brody shaves his head! (Or maybe he just goes instantly bald? Or someone shaves it?) Dana sexts and prays, Carrie cries and cries and cries, Jessica looks worried and put-upon, Saul looks penitent, and Quinn knows his way around weaponry. There's shooting, there's running, there's a lot of screaming, there's a little bit of making out, and there's a crazy wall and some kind of crazy-scribbled notebook that includes the item "You killed my son — prepare to die," which is a mangled Princess Bride allusion, of course.
