"Today my sons, we will enhance your senses. You rely too much on your eyesight. All ninjas must learn how to fight in the darkness, even when they cannot see." Cori looked around the room. The carpets were a motley of colors that didn't match. The walls were decorated with scenes of ninjas fighting samurais, ninjas fighting other ninjas, or small villages. Time passed quickly as she examined the room. "Don't you agree Cori?" Cori froze as Splinter looked down at her.

She hadn't been paying attention at all. She nodded slightly, hoping it was the correct answer. Splinter smiled a big grin and turned back to his sons. Cori started to gaze upon the room again and tuned out Splinter. She turned back to the turtles and saw them taking off their masks and putting blacks strips of cloth around their eyes. "Begin," Splinter shouted and the turtles got into fighting stances. They stood there for awhile until Donnie stepped forward. The floor creaked. Mikey, Leo, and Raph jumped towards that spot but ended hitting into each other. Once they hit into each other though they started throwing punches and tackling each other.

Each time they restarted the fight they did this again. At one point Cori couldn't help but laugh. Mikey had run into a wall and the others were walking around aimlessly. "Cori, what is so funny?" Cori looked up at Splinter and tried to pull a straight face. "Nothing," she said but she began to laugh again. "Yes, they are pretty hilarious," he said in a low voice so that only Cori could hear them, "Perhaps they need one enemy rather than each other." He held out his hand to help her up. "No I… Fine," Cori said with a sigh. Splinter helped her up and shouted "Yamei!" The turtles took the cloth off their heads. "Instead of fighting each other, you will be fighting Cori. She will however, not be blind-folded." Cori shyly walked to the middle of the room. "Make sure to go easy," Splinter said. "Don't worry Splinter, we won't be too harsh on her," Raph said. "I was talking to Cori," Splinter joked.

The turtles put back their blindfolds and circled around Cori. She stood there for a while, not knowing what to do until she said "So um, what exactly am I supposed to do?" She dodged Leo as he attempted to tackle her. "To see how long you can make it without being tackled," Splinter said. "I think I can do that," Cori said as she dodged a punch from Mikey. "Missed." Raph threw a punch and Cori easily blocked it. "Missed again." Leo went to kick Cori but she jumped out of the way and Leo hit Raph. "Ow!" "Sorry Raph." "Sorry my ass," Raph muttered.

"Raphael, language," Cori teased as she blocked a kick from Donnie. Raph opened his mouth to say something but he was interrupted by Mikey yelling "Booyakasha!" Mikey tackled Cori to the ground while she wasn't paying attention. "Did I get her? Or is it just Leo again," he asked. "No you got me," she said. Mikey got off her and sat next to her. He took off the blindfold. The scar from the night Rahzar attacked him was now a thin line. "Is that really how your face looks? I must've had the blindfold on too long," he joked as the rest took off the black blindfolds.
