While the flashbacks tonight will finally move towards setting Oliver up to be ‘rescued’ in the original Arrow pilot, the modern day fight will pit the Green Arrow against Prometheus.
All season long, Arrow has been using the threat of Prometheus to examine the choices Oliver has made over the past five years.
It’s also allowed the show to look back on its own legacy and how far things have come in the time since.
For the past five years, we’ve had a general idea where the flashbacks were heading given how the show started.
