Complete story — includes the ending
Cayden James attacks the city's critical internet infrastructure, causing numerous casualties, before demanding a ransom payment of $10 million a day to prevent future attacks. James reveals details of his vendetta against Oliver; a misfired arrow believed to be from the Green Arrow killed his son Owen a year ago. However, Oliver knows that he is not responsible because he was in Hub City at the time. Vincent claims that he is undercover with James' cabal and gives Team Arrow some intel. When one of James' attacks endangers William and his class during a field trip, Oliver is forced to reveal to his son that he resumed being the Green Arrow when he rescues him. Oliver and Quentin set up safe zones for citizens following the attacks; eventually, James' cabal targets them. Oliver and his former team put aside their differences and stop James' party's attack on the safe zones' occupants. Despite William being hurt by Oliver's lies, Felicity helps him see that it was with good intentions and gets him to accept his father's duty. Unable to find proof of his innocence before the deadline, Oliver gives into James' demands to buy time to find it.
