The first thing Olivia did when she stepped outside was to cover up the traces of amniotic fluid on the ground with some dirt.

She made it so that the trace of the fluid stopped at the intersection of the street.

When Wayne got there by following the trail, he found that the trail ended. He wanted to look for other clues when he heard some rustling noises from an alleyway nearby.

He drew his gun and approached the noise. Olivia was sitting behind a trash can with a blank look on her face.
