Andrew Hawkman was the main antagonist of the 'Sofia And Lucy' episode "The Scan". He killed a man named Harry Fenwell and disguised himself as a social worker while Sofia's mother was arrested when police thought she had murdered Harry. After it got dark he told Lucy to go to bed and asked her where the knife was as he said he needed to cut tomatoes. Lucy replies "It's in the drawer" and he goes out to murder Sofia's mother but his tag goes off and the police discover that he is the murderer and Sofia's mother pours toxic acid onto his face and it melts off, just like Harry's face at the start of the episode.
The Scans used to detect the murderer were flawed and only recorded people saying things about murder, Sofia’s mother still had a good reason to get locked up as she stated she was going to murder all the teen stars. Andrew Hawkman said he was going to slice Sofia’s mother which caused his alarm to go off in the Scan that he obviously forgot to give back to the researchers. Sofia’s mother grabs a bucket of acid out of nowhere and throws it at his face causing it to melt off. In the next scene, she is for some reason out of prison. The episode ends on a possible twist. It is unknown if Hawkman really killed Harry Fenwell due to the possible twist but
he still tried to kill Sofia’s mother.
Hawkman apparently wanted to get revenge on Sofia’s mother because she murdered his grandfather George Hawkman in her years of killing,
so he tracked her down, framed her and then planned to knife her.
