Cally was about to leave, when Lydia and Sarah both rushed over and slammed the door.
"What the hell?!"
Lydia smirked.
"You can't use the watch on multiple people, sis," she told Cally as she snatched the watch from her.
"You would've known that if you'd read the directions like I did."
Cally's heart was pounding wildly in her chest. Her fight or flight response was going off like mad, but at the same time, she found herself too afraid, too paralyzed by fear, to even move. This gave Lydia the opportunity and she swung the watch in front of Cally's face.
In a desperate attempt to avoid being changed again, Cally tried to turn away, shut her eyes, anything to stop it. But it was too late. She felt herself fixate on the watch and she relaxed.
Now possessing the upper-hand, Lydia decided what to do to Cally.
