The chosen one shows up to a masquerade that the evil wizard is at so he can kill him before the wizard poisons the guests.
The chosen one doesn't know who the wizard is because of the mask but the wizard knows who the chosen one is because he has Intel on what the chosen one is wearing.
The chosen one decides that he's going to throw a knife at the first person that leaves because that'll probably be the evil wizard because the wizard wants to get out of the masquerade so the chosen one doesn't kill him.
The evil wizard pays someone to go run out the door but the chosen one has a vision of this and he doesn't throw the knife at the man that runs out, instead, he throws it at the door and tries to cause a commotion.
Through all of the commotion, the evil wizard went outside attempting to escape and was found with a knife in his head.
Nobody knows where the man that ran out went or how the wizard ended up dead, all they know is there was no bloodshed from the wizard.
