Nothing, the feet do something instead

Before any of the two could react, One of Syntia's feet make Syntia's phone fall down off her hand and into the floor by pushing itself next to Gene.

"Hey!" she said. When she tried to retrieve her phone. Her feet pulled her out of reach. "Let me go."

"I'm not holding you." Gene responded

While Syntia still trying to reach her phone, Gene got out of hiding and get in front of her.

"Do you know that your feet are sentient" he asked her.
