Benjamin listened as all three explained about Frank, he couldn't stop a smile from forming. It was kinda cute to see and hear them talk about the same subject together. 
"They have nothing in common then," he said, crossing his arms. What could be the reason those three had disappeared? "We honestly need access to their files, there has to be something in there. Which means we need Sara, right now she's the only one of the staff we can trust."

Marc was doing some paperwork, but when that was done he decided to check on some patients, some had to be checked at irregular times to see they were not endangering themselves or those around them. Maybe after that he could check up on Sara.
