In Dr. Arden's examination room, Frank -- poor Frank -- is standing next to Grace's dead body on the slab, and he's having a moment. He's trying to apologize for, you know, shooting and killing her. In his mind, she keeps opening her giant eyes all accusingly at him. And, look, I liked Grace too, but she pretty clearly dove in front of that bullet all on her own. She knew what she was doing. He tearfully pledges to make things right. He turns around and is surprised by Dr. Arden, who seems very concerned by Frank's attack of conscience. Frank announces his intentions to tell the authorities all about Kit Walker's return to Briarcliff, about Sister Felicity (R.I.P.), and "that monster" what chewed Sister Felicity's throat out. Obviously, Arden's not in favor of this, so he reminds Frank that alerting the cops means confessing what he did to Grace, but, in one of my favorite moments of the season, Frank's just like, "Yeah, well, I'll own up to what I did." All that leverage Arden was sure he had on Frank just falls away. How simple for a good-hearted man to thwart evil by accepting the risks of being honest. Not that Arden is going to let matters go, but still. A for effort, Frank.
Devil Eunice is in her brand new office, listening to Christmas music and admiring the fire, when all of a sudden, there's a razor to her neck. Attached to that razor is Sister Jude, back in the habit (sorry) and ready to do battle with the devil. She monologues about how she wondered how a demon could walk the halls at Briarcliff, past all that religious iconography -- not to mention wear a crucifix -- without burning her flesh. Then she realized that it must be the otherworldly purity of Mary Eunice that is essentially insulating said demon. Sure, that's one explanation. Another could be that Briarcliff pumped so much evil into the world that all the statues and crucifixes housed therein have been sapped of whatever holiness that might have had. Or perhaps they've been caked with sin like a pickup truck after doing donuts in a muddy field. You know, so long as we're throwing out theories.
