PROMETHEUS MAKES A DEADLY MOVE AGAINST OLIVER AND THE TEAM — After Prometheus attacks Curtis (Echo Kellum), Oliver (Stephen Amell) realizes Prometheus knows all of Team Arrow's secret identities and is planning to come for them one by one. Felicity (Emily Bett Rickards) and Detective Malone (guest star Tyler Ritter) discover a clue that links Prometheus to Oliver's past.
