Tonight is the mid-season finale of Arrow — how is that possible? We need more eps to get us through the holiday season!

Anyway, we while plan on re-watching every ep of season five during that time, here’s the scoop on tonight’s episode:

In “What We Leave Behind”, 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.

Meanwhile, Felicity (Emily Bett Rickards) and Detective Malone (Tyler Ritter) discover a clue that links Prometheus to Oliver’s past.
