Tune in with Turner

 Last night Arrow gave us the new Black Canary aka, Tina Boland, whom we find out at the end is really Dinah Drake.  Of course we know that Laurel's first name was Dinah, so this is Arrow's new Black Canary.  She got her Canary Cry in Central City at the time of the  particle accelerator explosion.  She knows how to fight, because she had been CCPD  Clearly, Juliana Harkavy can act.  Her performance was both believable and authentic.  She holds her own with Oliver. As I have stated before, I know zero about comic books or comic book icons, so I had to do a little research as to why the showrunners found it necessary to give us a Black Canary, when there seems to be plenty on board who can help Oliver fight crime. Apparently the original Black Canary in the 1947 comics was named Dinah Drake, so this is a wink at history.  I guess the Green Arrow has always had a Black Canary, and since Arrow is taken from the Green Arrow, then it would seem...

From what is reported online, Talia al Ghul figures prominently into finding out who Prometheus really is.  I am thinking  we can rule out Adrian Chase,  since all that went down with Prometheus  and Arrow occurred while Adrian helped save John  Diggle from General who is trying to kill him. Did Talia give that information to Prometheus? Part of me wishes it would be Malcom Merlin, because it would be good to see him go down, but the likelihood of that happening is slim to none. Second  Chances  promises to be an interesting episode, and we will be back in Russia. Apparently Oliver needs Talia to help bring down Kovar, but she  wants something in return and Oliver isn't sure he can deliver.  What are your  guesses?
