Rudy Walters is a recurring character on How to Get Away with Murder. He is portrayed by Jack Mikesell.
In his room, it is shown there are a number of scratches above the headboard.
Mama's Here Now
Wes visits Rudy and when he shows Rudy a picture of Rebecca, Rudy utters the word "wet." Wes connects this to the fact that Lila was found in a water tank and is more suspicious of Rebecca.
Back at the apartment, Rebecca makes a phone trace of Wes's phone which placed him at the psychiatric hospital that Rudy is in.
The Night Lila Died
It is revealed that after Rebecca came home after finding Lila's dead body, Rudy saw her come home, and she invited him into her apartment and gave him a mix of drugs. Another scene shows him locked in his apartment, scratching the wall between their apartments, screaming and calling for his mother.
