That river in Egypt

When Damocles was putting in his passcode last night, he did it in her full view. She had taken a mental note of which keys he pressed, and when she took his phone to text his roommate, she also changed his passcode. She unlocked his phone with the new passcode and went through his search history. She read through and found that almost every search from the last 24 hours were related to Atlantis, where it was, why it wasn't found, who was looking, where they were looking. It turns out that apparently some guy called Graham was on it's trail, so at least somebody was looking into it? She wasn't sure why but even she was getting interested in it now. She had no idea what she was expecting to see in his history, but it wasn't that.
