The noise goes from hard thuds to a wet smush, wetter and wetter as Heine crushes the back of Eichel's head. Holding onto his neck rather than his head keeps his grip firm.

Time passes while Heine is listening. He doesn't really see anything; the strange sight of Professor Eichel's eyes staring into one spot in space, lightless, and the off angle of his neck seems to have gone far past shock to acceptance.

He lets go eventually and the body falls to the ground. A few pieces of cranium are only partially connected to the rest of his skull, now.

The sheer rage and joy that the dog takes from killing recedes. Heine settles back into his own body, shoulders dropping, presence fading. His limbs feel heavy. It's been a long time since he's done so much, and the effort of locking the dog away once more leaves him exhausted.
