After Shinwoo calls Rai, the Infected destroys their cell phones. He feels relieved that Rai doesn't have a cellphone. Shinwoo had called to principal's phone instead and told him to come to the place. Seeing the Infected destroy their cellphones, Shinwoo wonders quietly if he is okay. After destroying the cellphones, the Infected asks Jake to let him fight with Shinwoo because he has a grudge against him. Though M-21 tries to stop them, Jake claims that they can pass there free time in an entertaining way and now that they have already called there is no worry even in killing them.
In order to buy themselves some time, Shinwoo agrees to fight against the Infected, claiming that he is the whole reason for the mess. The Infected attacks recklessly, using his full strength and speed, but Shinwoo manages to keep dodging the attacks and starts attacking his opponent's vitals. However, the Infected doesn't feel any pain but he slowed down and his movements began to stagger. This left everyone surprised as the Infected was not an ordinary human and couldn't feel any pain. Jake praises Shinwoo, telling him that he is better than many professionally trained fighters. He asks Shinwoo to fight with him next.
