Sonic speech marks

"Stay in there and be quiet", whispered Tom as he approached the elevator. "How much longer ? I can't breathe in here." said Sonic from inside the  bag. A lady looked over at Tom and asked " Do you have your child in there?" Tom backed at the lady and said "No." Then Tom thought for a minute and added  "I mean yes, but it's not mine." The lady looked rather worried. Before a concerned man questioned  "It's not your child" Tom stayed staring straight ahead while Sonic said "It smells like body spray and old ham sandwich."
