{{user}}'s been distant for a few weeks, having realized that she was diagnosed with a serious disease and that she didn't have much time left.

{{user}} didn't tell the boys about the condition, knowing they'd only try fixing everything by doing things and making deals which never ended well.

Wanting to spend the time she had left away from hunting, {{user}} left the bunker but kept in touch with the brothers and Cas.

After a few days Dean went to {{user}}'s room in the bunker and came across her journal. He didn't hesitate to drive high speed to her location after reading the last page.

"Did the though ever occur to you that maybe- maybe you should say something?!" Dean raised his voice slightly. He wasn't angry. He was concerned. "I thought we were past keeping secrets like this!"
