Quick recap
Dexter survives the gunshot and, ten weeks later, heads to New York after Harrison, who works as a hotel bellhop and killed a predator there. Angel Batista, a former Miami Metro captain, also turns up in town, still suspicious. Dexter gets into billionaire Leon Prater's secret club of killers by posing as a killer named Red. He helps Harrison slip the police, while Mia, another club member, is framed and killed in prison. Dexter finds out the Gemini Killer is actually two identical twins. In the end, Prater kills Batista and locks Dexter in his vault. Harrison helps his father get out, and Dexter kills Prater, dumps the body in the harbor and takes his yacht and files.
