Shortly thereafter, Linker was cast as central character Lauren Hutchinson on the teen comedy/drama Square Pegs.
Square Pegs told the story of two high school freshmen, Hutchinson and Patty Greene (played by Sarah Jessica Parker), and their at times desperate attempts to fit in and achieve popularity.
Linker was forced to wear fake braces and a fatsuit in order to appear less attractive than she actually was for the character she portrayed.
Other notable roles for Linker were as Sherie Lee Fox in the 1985 science fiction film D.A.R.Y.L., and as Jenny Pennoyer in the 1984 TV movie When We First Met.
Linker appeared as the character Esmerelda on the television series Don't Make Me Sick in 2009.
