Why did they do this!?

Chapter Ten

Mikey's P.O.V.
Until...he came!
There was a shadow on the wall. It was laughing. Laughing and laughing. "Hehe~ Stupid turtles!" It chuckled. My eyes widened and I froze, I knew that voice well. Raph,Leo and Donnie looked around frantically. "Who are you!?" Demanded Leo. "Heh~ I am a shadow!" It said. I backed up. The others noticed. "Mikey?" Donnie asked concerned. "Anything left to say?" The shadow asked. "Chase..." Mikey muttered. "Chase?" Leo asked confused. "Ah, so you do remember me?" Grinned Chase. "How could I forget you?" Mikey replied. Raph, Leo and Donnie were really confused.
Raph's P.O.V.
This whole thing was super confusing. How did these two know each other? "Funny~ I thought you'd forgotten me by now" Said Chase. "After what you did? Pffft! That was unforgettable!" Mikey replied sternly. "What is going on? How do you guys know each other? And what do you mean by what you did was unforgettable!?" Leo asked. "You see Leonardo, Mikey and I used to be the best of friends..." Chase began. "So what happened?" Asked Donnie. "Well Donnatello, he betrayed me. Backstabbed me!" Chase growled. "Ya must've done something for Mikey to have done that" Raph replied. "But I didn't Raphael! He just attacked me one day! Isn't that right Mikey!? Always needing help! You worthless, stupid idiot!" Chase said. "Hey! Shut up!" Leo said, sticking up for Mikey. "Exactly what I mean!" Chase replied. At this point Mikey was fuming with rage. "S-Shut up!" He hissed quietly. Chase turned to look at him. "What was that Mikey?" He asked. Raph,Leo and Donnie looked worriedly at Mikey. He said nothing. Chase smirked. "What I thought." He said. Mikey still said nothing. "Right Mikey, guys, let's go!" I said, Leo and Donnie nodded in agreement. I heard Chase give a slight chuckle. "I don't think so!" He smirked whilst walking towards Mikey.
