Now we know the truth. Cadmus was never pulling the strings, but in fact it was Brainiac causing all this, manipulating everything. Just when you think Brainiac is gone forever, he just keeps coming back.
One of the best things about this episode was the action. It didn't matter who fought who, but the action was indeed spectacular, and Supergirl not only conquered her clone, Galatea, she conquered her own inner demons. Seeing Batman and Waller exchange words is never a letdown. The two seem to have a certain chemistry. Also, I was surprised that Waller actually had the founding members released. I guess even she can admit when she's wrong.
Now we know the truth, and everything that's happened since "Initiation" has been leading up to the final episodes of this season. It will be a pleasure to find out how this story arc concludes, and I will be right there to find out.
I hope you will too.
