I don't know if I quite understand what Zod is trying to accomplish here. I don't know why he isn't impacted by a ton of Green K around him. But that is more a commentary on the overall story. Let's concentrate on this issue.
Sophie Campbell does a solid job showing how Kara is trying to grow into her role of Heir to the House of El. How Kara is trying to be a leader for the El family in Superman's absence. But it isn't going to be an easy transition so seeing Kara doing her best to keep the team together on a dangerous mission into El Caldero is great characterization for our title hero. This is a Super-event so there are plenty of other characters here but Campbell really has Supergirl in the spotlight.
The art is a mix between Joe Quinones and Paolo Villanelli. The styles are quite different with Quinones being a more smooth style and Villanelli being more thin-lined, angular, and a bit rougher. The result can feel a bit jarring and I don't know if that is the best way to start an event either.
I honestly hope I understand Zod's plan at some point. But I don't yet. On to the issue.
