In the end, Aziraphale felt tears wrenched from his eyes, a by product of the emotion he felt. Fear and uncertainty, concern, most of all anger. Anger that Cassiel was gone, that Tegan was gone, that Crowley was torn apart by the loss.
He beat his hands against his demon's chest, buried his face against Crowley's shoulder. He could feel the sting of his tears on the other's flesh, the exchange of pain making them both more whole, for all that it broke them down.
