So, bringing back Roy Harper and Shado wasnt enough for The CW. Going all out, Arrow even brought back the ever-welcome Tatsu Yamashiro, aka the totally badass Katana. Not only does Katana look all kinds of lethal, we got to see her in action here against Nyssa al Ghul in what was a mightily impressive battle sequence as the two tried to best each other with their blade skills. Whilst some long-time DC fans may have felt that this is a dual that Katana shouldve actually won, it was still a great surprise to see Tatsu turn up and to see such a cool fight sequence play out. It was revealed here that Katana has been tasked with protecting the ancient Lotus, which we find out more on by the time the episode came to a close.
