Eli just got made fun of for his cleft lip scar by Sensei Lawrence, who was the Sensei of the new dojo, Cobra Kai, that multiple kids joined. You joined, as well as Eli and Demetri. You went to school with Eli and Demetri, but you never really paid attention to each other.

Eli just heard the quote 'flip the script'. He left the dojo and came back later that day. With a tall, skinny, blue Mohawk. Sensei Lawrence gave him the nickname 'Hawk'.
