She can't talk or move

Brianna opened her mouth, whirling around to give her "assailant" a piece of her mind. But as hard as she tried, no sound emanated from her lips. Her eyes widened as she tried again, clutching her throat as if something was wrong, but to no avail. She tried to scream- but no sound. Her eyes dropped to take a look at who it was, and they widened even further.

"What's up, Brianna?" said Jack, semi-sarcastically. Brianna's face narrowed into a scowl and annoyance, and her hands lifted what had just been shoved over her neck. A necklace? What the hell is this? she thought. A glittering, light blue crystal sat before her eyes. However, she wasn't stupid and narrowed her situation down to the cause being on her neck, and she tried to lift the thing off.

"Oh, can't let you do that," said Jack, who quickly tapped something on his watch. As Brianna's hands wrapped around the necklace, she felt a strong, powerful shock course through her body, causing her to give a yelp. A yelp? Could she make noises? The thought was pushed aside though, by the aftermath of the shock- what exactly had just happened?

"Not feeling so hot, are we Brianna?" joked Jack. "Just to let you know, any attempt to take off the necklace on your part is gonna result in the shock again. In case you're wondering, I've also cut off any attempt at calling for help or notifying others of your predicament."

Brianna's eyes went wide. She tried to yell, but then, remembering what Jack had said. "What...what have you done? What is happening to me?" she said quietly, her voice livid. She remembered her rejection of Jack, thinking that he was so far below her. She knew that she would have made Jack bitter, especially given his humiliation in public. But she never thought that something like this would happen!

"Well you see, Brianna, I happened to come across a very special necklace. And along with this necklace, I can do anything I want to you..." said Jack, raising his hand," ...with this watch on my wrist."

Brianna was taken aback. "No... no way does something like that exist!" she said, defiant and angry.

"Or does it?" said Jack, smiling. "Well, now that that's over, lemme just let you know about your condition-"

Brianna ignored his words, cutting him off by surging forward and preparing to deliver a slap, as well as trying to get out of her situation in any way. But something stopped her in her tracks...
