—Abby to Sam[src]

Abby DeWitt was a supporting character in CBS' Under the Dome. She was a resident of Chester's Mill that had an alcohol problem. She also had a daughter named Courtney who was taken away from her by social services before the dome came down.

Before the DomeEdit

Hardly anything is known about Abby's life before the Dome came down except that she lives in Chester's Mill and has a daughter, who she mentioned was taken away by social services due to her drinking problem.

Under the DomeEdit

Season 3Edit


Abby goes to the meetup at the school. Sam asks her if she would like water he got from his well. Abby denies his request and listens to Big Jim talk about how Melanie Cross was responsible for the cocoons and the alternate reality. Abby is mad about it and partially blames Barbie. Later on she is one of the people who go to the support group. She talks about how she was giving her daughter a bath when the alternate reality ended and that she can't lose her again.

"The Kinship"Edit

Sam finds Abby attempting to hang her herself and saves her. He comforts her, and after both drink, they end up sleeping together.


Abby wakes up to Sam getting dressed to go to work. They cuddle for a moment and share a kiss before he heads out. Later, Christine stops by Abby's and guilts her about how her drinking caused permanent brain damage to her daughter. She advises her not to ruin Sam's life as well and suggests suicide by handing Abby some pills. Sam comes back to find that Abby has drowned herself in the tub, presumably due to an overdose.


Abby's corpse, although only her hair, is briefly seen when Sam sees her for the last time.
