User blog comment:TheDoctor230/My Thoughts on the Crossover/@comment-3127448-20171204081244

I felt like this crossover had quite a few plot holes: 1: Where the heck did Oliver get kryptonite from?

2: How does everyone else know about kryptonite? It was never explained to the E1 people that is Kara's main weakness.

3: During the church fight scene, where the heck did Oliver get arrows from? We saw he hid a bow but not the arrows nor was he carrying a quiver.

4: Last year, Barry introduced Kara from another earth. So why didn't Jax know about more than one earth?
