Editing LJ Folger (section)

===Snowpiercer Murders===
When Layton is hired as train detective, LJ is skeptical, but does not openly discuss the matter unlike her mother, [[Lilah Folger|Lilah]]; LJ keeps quiet, but is observant.<ref name="s1e02">''[[Prepare to Brace]]''</ref>

Later, following Fight Night, LJ is among the residents of First who is questioned by Layton. She reveals that [[Erik]], her bodyguard, did not return home that night. Layton immediately suspects Erik, and Melanie sends [[Bess Till]] to locate him. It quickly becomes clear, however, that LJ is sadistic and is actually the one behind the murders. Layton is quick to realise this, and LJ — fearing being caught — tries to bargain with Layton for blueprints of the train or eventually, weapons. Layton acts as if the deal is done but secretly alerts Melanie to LJ's crimes.

Layton announces to LJ's parents that LJ is the mastermind behind the murders, and Erik was acting out of love covering for her. LJ swings at Layton with a blade but is tackled to the ground before she can do any serious damage. She is later imprisoned in a cell as Melanie makes an announcement about the apprehension of the serial killer.<ref name="s1e04">''[[Without Their Maker]]'' </ref>
