Please . " Dean looks away , eyes wet and Sam just nods and takes the money from him , slips it into his pocket , unsure of what to say , but Dean does n't leave him the opportunity to say anything before he hurries from the room . The next day Dean drives Sam to the bus station , the car is filled with a palpable silence so thick Sam feels like he 's suffocating . Words unsaid hang in the air between them as they both pretend they 're fine .

Question: What may be the reason for pretending to be fine ?
Answer: They 're protecting each other .They are trying to be strong just for themselves .They actually are fine and want them out .They are n't pretending .
