Harry sat straight up and grabbed his phone from beside the bed. He had not had a phone until he came home but Severus had bought one to keep in touch with Abigail and Penny. Harry had bought one so Severus could call if he needed him. He opened the timer app and they waited. When the next one hit they timed it it only lasted a few seconds and there were twenty-two minutes before the next one which also only lasted a few seconds.
