Faith has a slayer dream which sends her on a reluctant journey to her old territory, on a quest to save a new ally.
Previous parts are here. "Castiel!"
"I cannot raise my hand against them," he says, gasping. "The mark--"
The leader moves in on him, bloody knife in hand. There's a tattoo on the back of its hand, some kind of magical symbol.
"Get down!" she shouts, and Castiel drops to the sanctuary floor. Her sword slices the air and neatly hacks through the demon's forearm.
The demon falls to its knees beside the knife and its hand, howling. Castiel struggles to his knees and plants his palm on the Sweeney-demon's forehead. Light pours out of the demon's eyes and its screaming mouth, then it falls to the floor. The other two are transfixed by the destruction of their leader until one of them shakes off its shock and lunges for the knife, while the other attacks Faith. She drives it back, and it blindly stumbles over the other minion, sending them both sprawling.
"Castiel!"
"I can't. They have it too."
Her opponent scrabbles on the blood-slicked floor, bringing up a wicked looking machete. Before it can get much into the swing, Faith brings her own blade around and slices through its arm too.
The third demon has an arm around Castiel's neck, bringing a knife up poised to slash across his throat. There's no way she can cut the minion without wounding or killing Castiel. The demon hauls Castiel to his feet and backs toward the front of the church, pulling Castiel along with him. Faith suddenly gets a fully-formed image of what this seal is about: an angel's blood in the baptismal font. Whether it's one drop or every last ounce she doesn't know, but she is not letting this happen.
Faith brings up the bottle, slashing out with the holy water as she would a blade. It's a broad, sloppy stroke, but the liquid catches the demon in the face and eyes, and it loosens its grip on Castiel, screaming.
Castiel drops down and Faith swings her blade, severing the demon's hand at the wrist. Castiel draws himself up and plants his hand on its forehead, consuming that one in light too.
She looks around for the last one, disarmed -- ha, literally -- but not dead.
It blindsides her, crashing into her and knocking her into Castiel. With its remaining hand it snatches up the bloody knife, with the other demon's hand still closed around the hilt. It whirls and makes a move for the baptismal font.
"No no no no no!" Faith yells.
Steve, who was released from whatever held him when the leader died, rises up from where he'd fallen and tackles the demon. In a heartbeat she's on it too, wrenching the knife from its grasp.
"You won't stop this, whore," it says. "Not even the angels will stop us."
"This 'whore' shit is gettin' tired," she says, and runs him through with her blade.
Castiel has gotten to his feet, though he's unsteady.
"Stay back," she tells him. "I don't want your blood anywhere near that font." She hoists the dead weight of the demon up, dragging it to Castiel. "Finish him."
"Next time you're in hell, it won't be a short walk-through," the demon tells Castiel. "We're winning."
Castiel lays a hand on the demon's head and it screams as light pours out of its eyes and mouth. He staggers as the demon falls in a lifeless heap.
