In case there were any doubt Arrow would survive the four-part alien “Invasion!”, we’re already looking past the crossover to the series 101st episode, and a 2016 finale at that. Find out “What We Leave Behind” in the first photos, as Oliver finally takes on Prometheus, and returns to a classic look from Season 1.

The CW released the official photo set from December 7 winter finale “What We Leave Behind,” featuring what looks like a return to the early days of the series, judging by Oliver’s costume, and a shot from the original lair. Prometheus’ identity has been said to tie back to Oliver’s early crime-fighting days, so might “What We Leave Behind” finally lift that raggedy mask?

Here’s what the full synopsis has to say:

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.

In the meantime, Oliver will be busy fighting aliens (and reliving the past) in its 100th episode on November 30, so check out the trailer below, and stay tuned for a fresh look at “What We Leave Behind.”
