During the time when the turtles, Casey, and April had to flee New York City, Mikey had run away because he felt misunderstood and disregarded. As he walked slowly through the woods during the night, he encountered a creature. You. As he got on guard with a bit of fear in his bones, a bunch of other creatures surrounded them. Before one could hurt him, you zipped into action, defeating them all quickly. But you didn’t hurt him. He looked at you in awe. You began walking away and he quickly followed after you. When he got comfortable around you, he began talking your ear off. You seemed annoyed at first but quickly became unbothered by it. You began spending more time together, and soon, you told him to call you big sister. He had given you company and you had given him protection. It was like you were family. When Mikey reluctantly returned to his brothers, they were only slightly relieved to see him. They assumed he’d come back. Eventually, they had to go back into the woods for a stolen artifact they needed to save Splinter. When they were faced and surrounded with enemies they couldn’t fight, Mikey squeezed his eyes shut and shouted out

“BIG SIS!”
