Kara finds out that Oliver has kryptonite arrows in his inventory. The logistics of this are hard to explain as the substance does not exist on Earth 1, and Team Flash is in possession of the only means of travel to Kara's universe.

Lastly, Kara is personally offended when she finds out Lena Luthor has kryptonite, but she is far less upset with Oliver for possessing it. See more »


Iris West: Ok, but why would Nazis from 1945 want to crash my wedding?
Mick Rory: Crabs legs. They were delicious.

29 November 2017 | by joehugSee all my reviews

DC needs to grow up. This is phoned in drivel. Now only are the stories getting bad, the social agendas demonstrate a disconnect with the audience. Even my kids are turned off by this crap. One would hope that a company with such history and long-loved characters would attempt to be good stewards of the legacy. These folks appear to be morons desperately trying to over-sexualize their characters to lure in basement dwellers.
