The battle for Starling City really gets going in episode 22 of “Arrow” Season 2, “Streets of Fire.” With Slade Wilson’s mirakuru army wreaking havoc all over, it’s up to Oliver Queen and Team Arrow to save the city … again.

This time, however, Oliver might actually get a little help from Malcolm Merlyn.

Watch the video promo for “Streets of Fire” to get an idea of what might come next.

While most of the video details chaos and little else, there are a few points that one might want to note. First and foremost, Merlyn (John Barrowman) is back in town — and back from the dead, as far as all of the characters are concerned. But he may not want to destroy everything this time.

Others appearing in the video include the District Attorney (the woman Laurel Lance keeps besting in verbal altercations), Isabel Rochev (not looking happy), Laurel with a bow and arrow, and Thea in a whole bunch of trouble.

Can Oliver save the city? Will Slade Wilson finally get his revenge? Find out when “Streets of Fire” airs Wednesday, May 7 at 8 p.m. ET/PT on The CW.
