When Erik knocked and still didn't get an answer after knocking again a minute later he pulled out a phone from his pocket and called Katy's phone then hung up after it had rung one time. When Greg smiled with an arched eyebrow Greg explained, "That's my contact phone she calls to give me what she thinks are full reports. The one ring is our code telling her I'm here. And, if I hadn't of known basically from my first time having to go to some of his girls and them all acting the same way when I would ring that pattern, I would have thought that Heflin had gotten the idea for those doorbell patterns from breaking Katy and her telling him about us doing those ringtone patterns."
