In Wednesday's episode, Betsy's fate is revealed after she was rushed to hospital for emergency treatment.
A doctor confirms that the bullet has been removed successfully from Betsy's shoulder, but the incident could have permanent consequences for the teen.
He tells Carla and Lisa: "The bullet was lodged in her upper arm, causing swelling near an adjacent nerve. She was given a blood transfusion due to severe blood loss.
"We need to carry out more tests to assess the extent of the damage. I'm very sorry, but we are potentially looking at a life-changing injury for Betsy."
