Gabby was working with Meg for a while, but then things went south, and they ended up snapping her neck. Later on, she's in an apartment with John Winchester, but she guessed it was a way to get the boys to save them, but little did they know that a demon was possessing their father, but not any demon, but a powerful yellow eyed demon. That they all have been hunting for awhile, and John years. Gabby was caught in the middle of it all, after all she was the one who let the demon inside John, but in her mind she was protecting Sam and Dean.
In the end, they knew that it wasn't their dad and then began the pain. Luckily, Gabby got their just in time to try and save them, but was too late to do anything. Because she was a monster, and didn't want the boys to know.

Sam got out of the hold from the demon and shot his dad's leg, but his dad told him to shoot him to kill the demon, and get it over with, but Sam couldn't kill his father, and Dean didn't want that too. Dean was also hurt badly, blood everywhere on him. The demon left their Dad, and went away. Thus began the hospital trip for Dean and John, but they didn't make it to the hospital, a truck came out of no where and rammed the Impala, smashing it up to hell leaving everyone damaged or dead...

And Now...
