'Stop it, there is no need to hurry,' Tom thought to himself, dashing forward without the slightest care in the world. 

He would run only through the shortest corridors that he would find. Whenever a long one would appear, he would throw his spear, conjure another one in his hand, swap places with the thrown one and repeat the process.

'Why are you even in a hurry?' Tom continued to try to argue with himself, unable to understand the sudden duality of his thoughts and actions.
