Katherine didn't want to think about what Clara and Marshall would be discussing on their journey. There was nothing she could do about it, so she didn't want to trouble herself with it. After some time spent unwinding in bed, Katherine used her phone to play the game, but Marshall had not returned yet.
Katherine was clueless as to Clara's address. Was that why Marshall had waited so long to send her back?
Alternatively said, Marshall was invited to visit Clara's family since they were so welcoming. After waiting for a little while longer, Katherine left the room.
There was nobody downstairs when she made her way to the second-floor stairwell. Katherine tiptoed downstairs and made her way to the living room's corner. This place appeared to have an underground cellar, as she recalled.
