Zach is walking home at 4:00 A.M. but runs into a random guy in a back alley who frightens him half to death. Zach then thinks it is a test by the same people who tested him before.
Zach then feels like he is being made fun of so he begins to contemplate if he should stand up and fight or just walk away from the fight.
Zach goes and pins the guy into a corner where the guy becomes scared and Zach realizes he is a normal guy. This scene is significant because it shows that Zach's powers have gone to his head and does not know what is right from wrong.
