"Master, be careful, okay?" Derek said as he unsheathed his sword. "I'm different from how I was two years ago. If you're not careful, I might accidentally slash you."
"I understand," Thirteen answered as he wore a Crimson Armor that covered nearly his entire body. "I will also fight you seriously."
The teenage boy knew that Derek had improved a lot under Camazotz's guidance. So, he decided to test the swordsman's skills without holding back and see just how powerful he had become after two years of training.
"Are you ready, Master?" Derek asked while pointing his sword in Zion's direction.
"Ready," Thirteen answered.
As soon as the teenage boy confirmed that he was ready, Derek charged in Thirteen's direction.
Although he was fast, it wasn't fast enough for Thirteen to not see his movements.
The teenage boy smiled faintly behind his helmet because he already understood what Derek was trying to do.
