Alexis & Tim Murphy's Mother's Boyfriend (C/N)

A balding man younger than Tim and Lex‘s biological father, Mrs. Murphy apparently knew him from work. Tim suspected his mother had a boyfriend, but he never wanted to tell Lex. He apparently treats the children fairly, but Tim thinks that the man is simply trying to get on his good side by being nice. Mrs. Murphy and her boyfriend argue on occasion, which Tim can overhear when using his computer late at night.
