Mimic was doing her usual messing around, as someone else, when a somewhat familiar character appeared to 'stop' her. She played with him for a while, like a game of cat and mouse. She seemed to think it fit the character she was playing.
"I thought you'd of figured it out by now" Mimic's words echoed through the warehouse from the rafter she was in, while watching Nightwing look around. He suddenly put away his weapon and dropped his defensive pose.
"Alright, you're not who I thought." He called through the place.
"Bingo!" Mimic dropped from the rafter and landed behind Nightwing. "Now I wonder what in the world would've given me away?" Nightwing turned to face her "Oh! I know. It was that voice wasn't it? Shoulda kept my mouth shut, we could've played this for hours"
"For the world's greatest copycat, you suck at voices"
"I guess I should probably work on that at some point." She turned and started to leave "See ya later Dick"
"Wait." He said as she reached the door "How do you..?"
"Raised by the Bat and you don't know?" She only turned her head "Oh Mr. Greyson I'm offended. I guess you're not as smart as I gave you credit for." And she left without another word. Nightwing was left puzzled 'How does Mimic know his secret identity?' 'What else does she know?' He ran outside to see if she was still close. But all he saw were empty roads and factory buildings.
