They spotted Sarah across the street. Her on-again off-again boyfriend lived only a block away from Jon, and she'd often passed his house on her way there...deliberately walking on the other side of the street from his house.
She was talking on her cell phone, with a wireless headset on her ear. They could hear her side of the call. "And I told him if he wanted to be anywhere near me, he had to get rid of that..." Suddenly, the headset began to grow and Sarah trailed off. As they watched, metal stalks entered her ear. A few moments later, another stalk grew out the other side, growing into what looked like another headset.
Sarah began to stumble, almost robotically...as if something was trying to learn to use her body, and doing a series of tests.
