Sonic Using 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 looked back at the lady and said. "No!" Then Tom thought for a minute and added. I mean yes it's a child, but its 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. "smells like body spray and old ham sandwich!"
