Tricky

The brace on Leonel's wrist vibrated, and all the accumulated tremors of his earlier hammer surged. 

Jones felt the pressure building in his head as the horror set in. 

His skin began to bulge from the blood pressure, his skull deformed soon after as his brain pushed up against its mold, and then his eyes popped out of their sockets in a rain of blood. 

All the while, Jones wasn't able to make a single sound. He could only scream in his own thoughts, trapped in the cage of his own mind as it became a murky, disgusting mess of gray matter oozing from his nose and ears. 

Then, he couldn't withstand the pressure anymore, and his head exploded. 

A shocking silence filled the city streets. There had been many spectators that had gathered by now. After all, the Kammy smithy was on a busy street. Their residence was the only one here, while there were many other commercial properties that the people would frequent.
