Dexter's relationship with chief Angela is badly strained after she found out he changed identity, but he manages for now to make her believe to be innocent. Dexter finds out that Kurt is a serial killer, fails to keep Harrison away and arrives at his wood cabin with murder dungeon just in time to prevent him eliminating blogger Molly Park and Angela there. Harrison's dark side reemerges gruesomely in a school wrestling match, meanly co-coached by Kurt, Dexter doesn't know how to handle it and joint therapy only seems to estrange Harrison further. Assuming Kurt covered Matt's tracks, Angela finds her long lost friend Iris's corpse in Clark Caves and calls Dexter for his crime scene analysis skills.
