Mackenzie wasn't expecting to hear Tatum's voice below her after she dropped the apple core, and she was extremely put off by the other girl's tone. She had been so hopeful at having a decent day a moment ago, and yet fate had stepped in once again, delivering the redhead right to her doorstep. She decided that if Tatum was going to treat her like a scum bag when she had been trying all day to be nice, she was going to just give in to what the other girl clearly saw her as. Stubbing out her cigarette she smirked smugly, knowing exactly the kind of reaction she was going to get.
"Look out below!" She yelled, cackling happily as she launched herself from the branch into open space. She hadn't climbed that far up into the tree, she had fallen farther from her broom during Quidditch, but it was still far enough to make a scene. Crashing through the branches a little, she managed to land almost on top of Tatum.
Picking herself up off the ground, she brushed off her sweater a little bit and adjusted her scarf. Grinning obnoxiously, she cocked her head to the side and stared at Tatum. "You need to chill out kiddo," she informed the other girl, she reached out and ruffled Tatum's hair by way of messing with her hat. "Sera didn't do 'nothing wrong, you're bein' a poor sport. It's not like anyone is forcing you to like, sleep with me or marry me or anything."
