Tom knew the procedure by heart: When you’ve been shot through with an arrow, break off the end with the fletching and pull the arrow out by the head. Put pressure on both ends until medical assistance arrives.
So, when the professor shot him in the leg with an arrow, he broke off the end with the fletching and pulled it out by the head. Then he tore off a sleeve, bound the wounds, and applied pressure.
“Pass,” said the professor.
The medics injected Tom with the regeneration nanobots, and he watched the professor nock another arrow.
“Next!” he shouted.
