Elsewhere, Canary and Detective Lance are fighting together to save Starling City from the devastation two forces have thrust upon them: Slade and Amanda Waller.
It seems all is not lost on the Arrow Season 2 finale, however, Diggle confronts Amanda regarding her nefarious plan to turn their city into a crater. It doesn't look like she's going to have a lot of support. Diggle, though, receives plenty from new and old friends, Deadshot and Lyla.
When Oliver comes up against Slade, he has a decision to make. Does he hold to his mantra of no killing or will he do the unthinkable to stop a monster?
