I've been wondering exactly where this comic could go, and this volume heads off in some interesting directions, in large part because it chooses to focus on Tracey rather than Leo. It also looks like there might be increasingly interesting interactions with the universe that our protagonists originally came from. 
 At this point, I don't feel like this comic is pushing the boundaries of superherodom too much. But, it's a bit different from typical superhero fare, and that's fun, so I've continued to enjoy it every now and then.
