Mary-Sue explains things

Tea wasn't sure how long she walked; the trees were evidently further away than they looked at first glance. All she did know was that during the whole walk, she found absolutely nothing - nothing to cover up with, no signs of where she was, not even any evidence that other people had ever been here. It was just grass as far as the eye could see until the tree-line. Reaching said trees, Tea groaned and leaned against one, sliding to the ground and rubbing her sore feet.

"This is ridiculous," she grumbled, "I don't know where I am, I don't know where I'm going, I don't even know if I can get home from wherever this is, and I'm still naked! And all because some psycho fangirl was jealous of me being friends with Yugi?"

"Don't act like you weren't seducing him, you hussy," Mary-Sue's voice hissed. Tea jumped in surprise and scrambled to her feet. Looking around, she saw a glowing portal on the ground, Mary-Sue's face glaring up at her through it.

"What the hell?" Tea asked, blinking in confusion.

"Part of the Millennium Bracelet's powers," Mary-Sue answered, "It not only allows me to create and control this lovely pocket dimension you're currently in, but also allows me to communicate with anyone inside it."

"Wait, pocket dimension? I'm not on Earth anymore?!" Tea exclaimed in panic.

"That's right," Mary-Sue replied smugly, "I was tempted to dump you somewhere in the real world, but I decided it'd be more fun to leave you in my personal playground. That way I can punish you for however long I like for daring to try and take my Yugi away from me."

"I didn't know you existed before today!" Tea protested, "And I doubt Yugi knows you exist at all!"

"Shut up!" Mary-Sue snapped, "Don't you dare besmirch our true love! You know, I was going to go easy on you and just leave you in that pleasant woodland, but now I think I'll make things a bit more difficult!"

"Difficult?" Tea asked, fear spiking as she suddenly realized she was at this lunatic's complete mercy.

"Yes, but the question is, what should I do? Fill those woods with flesh-eating monsters? Turn it into a barren wasteland? Or maybe a tundra, so you can freeze those stripper tits of yours off?" Mary-Sue giggled evilly, "So many possibilities. What do you think?"

"I, I, I, I," Tea stammered, before suddenly spinning around and running into the woods in a panic.

"You can run, bitch, but you can't hide! Not here!" Mary-Sue laughed, her Millennium Bracelet glowing as she focused its powers on the pocket dimension.
