Character in Hamlet. He is Hamlet's BFF, much like Wallace is Veronica's. Wallace finally learns that there are more things in heaven and earth, than are dreamt of in his philosophy, when Veronica confides in him. Even if there might be cause to question her sanity, let's hope that like Horatio, he sticks around to the bitter end. Horatio's name is on the board in 1.07 "The Girl Next Door."
