I Think I'm Gonna Like It Here

Ness Singer-Winchester has been a busy, busy girl for years on end now, and this year is just as busy as all the others. If not more.
Her brother-in-law Sam Winchester is possessed by the angel "Ezekiel"/Gadreel, just to keep him alive because of the aftermath of the trials that had nearly finished Sam.
Her husband Dean? All he does is worry about Sam and Ness, and doing their job. He's also very worried about losing Sam after what he did to protect him.
And Ness is trying her best to make sure that Sam and Dean don't fall apart, even if it means that she falls apart herself in the process.
