Alex was a brat
She was a disrespectful little bitch to put it kindly. I don't care how crazy her mother was, her attitude towards Carly was terrible, and it seemed to be worse whenever Daddy wasn't around.
She made Carly call TLJ when he was away on a job - how would that help anything? She wanted to play a joke on Carly by making it look like she was dead. Imo she treated her mother like that because she though she could because she was "crazy". I wanted to slap her myself.
