While Damien was on the counter of the cafe, Katherine, Alianna, and Caroline played with their phones. Katherine was texting with Emma, planning about when they'd see each other next. As she held her phone with her right hand, it suddenly shook uncontrollably. The more she tightly held her phone, the more her hand trembled.
This wasn't the first time that she'd experience this, so although she was surprised, she hid her panic well by transferring the phone to her left hand. The trembling stopped. There was a tiny current buzzing within her, mostly at the base of her spine and then her right hand. It started while she was recovering after the whole Shadow fiasco. But she associated the tremors as side effects from Adrifin, the drug that was administered to her when she was rescued last month.
