Together now, as Al's fingers curled around the bone handle of the stirring rod, as he offered his strength and effort and contributed to the practiced-and-learned motions at last, controlling it and letting Severus control it as well, again and again, counterclockwise. Al could do this now with his eyes closed if he had to.
He looked up at Severus, a smile in his stare, smile stretching his lips. He leaned back, letting his body do what his hand had done before, shadowing Severus' position and stance, and movements. He felt warmth from Severus' breath and somehow it was more significant than warmth from the cauldrons.
Warm and quiet. It was peace in the silence shared by two.
