Keppler is a drug dealer who is targeted by the LAPD.
Matt and his partner head to Long Beach, CA to capture Keppler. They enter Keppler's home after receiving a warrant, and they soon capture Keppler and tie him to a chair. However, Keppler refuses to tell them where the drugs are stashed. Matt's hallucinations of Sylar misguide him into thinking that Keppler has kidnapped killed a little girl. When Matt begins punching Keppler violently, his partner restrains him and Matt realizes that there was no little girl. Keppler was knocked unconscious, however, and Matt's partner accosts Matt and warns him that he'll need a good lawyer to explain what he did.
