Christian could hear metal clinking against itself and surmised that Sam was playing with some copper wires or something else she'd found in the trash heap. He almost felt jealous of Sam. Her power seemed to give her direction, it was like someone giving directions while you're driving. To Sam they were giving clear instructions 'go twenty meters and take a right' to him it was more like 'STOP SIGN!' while they snapped there fingers in his face.

"Unless you see Safeway around could we move on?" Then he realized that Sam had had her card stolen by the thief that he'd been chasing before he'd changed direction to see if she was alright. "Oh sorry, I forgot." the floating objects immediately fell to the ground. 

"What was that?" he asked cocking his head listening for anything else. He decided it was likely just someone dumping unwanted garbage nearby. "Listen you can share my card, I'm not going to spend eight hundred dollars."
