Not sure which episode the cast was filming for when these shots were taken, but no doubt it will be exciting stuff from here on out for the rest of the season of Arrow.  One thing to speculate is that there will be confrontations between Roy Harper (Colton Haynes) and Thea Queen (Willa Holland) against Oliver Queen (Stephen Amell), while Felicity Smoak (Emily Bett Rickards) has startling news for Ollie, while Malcolm Merlyn (John Barrowman) basks in the joy of unnerving the hero archer.

Hmm… Roy sure does like his red hoodie.
