Say Hi To Our Mutual Friend

Finding them hadn't been terribly difficult once he knew about Four and Five. A little internet research into Finn Robinson lead to a Facebook account. It was private so he couldn't see anything but profile and cover photos but one of them caught his eye. 

It was a picture of six people standing in front of a waterfall wearing athletic gear. He recognized five of them despite the fact that they were smiling widely, had hair, and were posing like targets with their arms over each other's shoulders. 

It seemed that Seven, Eight, and Nine had left that night as well. It was the only explanation for them still being in contact with Four and Five. But who was standing next to Eight?

Several people were tagged in the photo so he was able to learn their aliases. Carmen Rodriguez, Michael and Sarah Williams, and Cody and Karli Osborne.
