Meg was born in Andover, Massachusetts, and she attended a local high school. She meets up with Sam for the first time in “Scarecrow” when she is on the roadside heading for California to get away from her family, or so she tells him. The two meet up again not too long later at a bus station and wait together for the bus to Sacramento to arrive. Sam tells Meg about Dean and how he seems to treat him like dirt. After Sam leaves to help Dean, Meg kills a man in a van and ‘makes a call’ by slitting the man’s throat and draining his blood into a silver bowl. She refers to the person she speaks with in the bowl as her father.
We again met Meg in the episode “Shadow” where she is in Chicago at a bar. She tells Sam that California was not all it was made up to be, they decide to meet up later. Meg gives Sam her phone number, 312-555-0143, and her last name, Masters. Sam later follows her to a warehouse where he finds her talking with something. Sam returns to Dean and tells him what he saw, they arrive at the conclusion that she was the one who summoned the Daeva (the evil of that episode), and she might have been talking with the Demon. Meg captures the brothers and reveals that their capture was a trap for their father. After breaking free, the Daeva sends Meg crashing out of a seven-story window to her apparent death.
However, Meg somehow manages to survive. We see her again at a church where she speaks with Pastor Jim Murphy, showing signs of being possessed, before she kills him. She later calls Sam and asks to speak to John. While on the phone, she kills a friend of John's, Caleb, and tells him that if he does not deliver the Colt gun to her by midnight in a warehouse in Lincoln, on the corner of Wabash and Lake, she would kill more of his friends. John agrees to the deal, despite how long it will take to get there. John makes it on time but gives her and her companion, Tom, a fake gun. Tom shoots Meg and reveals that it is a fake. Meg then takes John hostage.
Meg then comes to a friend of the family’s, Bobby Singer's, auto shop and is taken captive by Dean, Sam, and Bobby. There they are able to get information on where their dad is. Dean then forces Sam to finish the exorcism on Meg, releasing her from the hold of the Demon’s child that was controlling her. Meg reveals before she dies that the demon had possessed her for a year, in that year she was awake through some of it.
Her last word was "sunrise", directing the brothers to the Sunrise apartments, where their father was held.
She reappeared "Born Under A Bad Sign," sporting Sam's body. Not caring any longer about the grand war, she was just looking for revenge after Dean and Sam sent her to hell. After tying herself to Sam with a binding mark, she taunted Jo about her feelings for Dean, tried to kill Bobby, successfully killed another hunter, and attempted to kill Dean after breaking the Key of Solomon being used to trap her. Fortunately, Bobby burned off the mark and Meg fled. Current whereabouts are unknown.
