‘Arrow’ season 5 photo: Oliver Queen and Supergirl meet!

Apparently, having Deathstroke is not enough for the 100th episode of “Arrow” — you’re also getting something else that is rather awesome in the process.

In the post below via star Stephen Amell’s official Twitter, you can see his Oliver Queen for the first time alongside “Supergirl’s” own Kara Zor-El a.k.a. Melissa Benoist. These two characters have yet to share any time together, so having them do so here is a pretty momentous occasion.

We knew that this moment was going to be happening for quite some time, but there is one question that remains: How? Obviously, Oliver cannot travel to wherever Kara is in the universe, while at the same time we haven’t gotten the sense that she has figured out to travel from one world to the next.

Another question that we have is how in the world Oliver can be effective against some “Supergirl” villains, given that she is significantly more powerful than he is and her villains are typically put on that level. Basically, she cloud probably defeat some “Arrow” villains in around ten seconds, so it really doesn’t seem like a fair fight. We’re assuming that this is for episode #100 given that this is what the show has been filming as of late, and if that is the case, the Big Bad is likely to be some sort of Deathstroke. There’s no guarantee that it will be the Slade Wilson version, though, given that there is no evidence that Manu Bennett has been on set as of yet.
