Plot
Brave and The Bold - Oliver, Roy, and Diggle track down the location of a boomerang-wielding killer named Digger Harkness but are surprised when they come face to face with an A.R.G.U.S. team. Diggle asks Lyla why A.R.G.U.S. is involved but she defers until Harkness attacks the building, killing several agents and targeting Lyla. The Arrow joins the fight and gets help from an old friend – The Flash
Thoughts
Now, what I like about Flash vs Arrow is that the meta-human who caused people to lose control of their emotions, is that the lesson in all of this is that sometimes, our emotions can get the best of us if we let them run negatively. And in Brave and the Bold, sometimes you can't do things on your own. Working together can do more, much more.
Conclusion
God Bless and Enjoy The Show!
