The issue, per usual, begins with the preview. Laura pursues the Cuckoos, vaulting across cars to catch up with their van. However it's not until she gets it to stop that she realizes she's been had; the Cuckoos planted Gabby's goggles on a random vehicle to throw off her ability to track by scent, and used their telepathy for the rest.
Laura returns to the church and locates Dr. Marks, who is mildly confused to find herself there, rather than her lab. Marks tells Laura that she's moved on from cloning since the X-23 project, and is now working on grafting cloned memories onto an existing host. The material that she was given to work with was too badly degraded, however, and the cloned host bodies were unable to tolerate the parasitic relationship of the new pysche. Marks' research has led her to conclude that X-23 — and, by extension, her sisters — would make for ideal hosts.
Hearing this sets Laura off, and she lays into Marks over why she took back up the name X-23: So when she came after people like her, they would know WHY. Meanwhile, Gabby manages to get loose enough to activate her tracker, setting off an alarm on Laura's buckle. Laura departs with Marks still among the living, but makes it very clear that if she returns to her work, or if Gabby dies, she won't be for long.
Laura places a call to someone she hasn't spoken with in a while, while the Cuckoos strap a drugged and even more talkative than normal Gabby into a chair. She pesters them about their birthday, before noticing the increasingly decrepit Esme next to her. One of the Cuckoos (probably Mindee) is apologetic.
Meanwhile, Laura has regrouped with Warren for a ride and followed Gabby's tracker to the warehouse where the Cuckoos are working. She doesn't clue him in on what's happening, and makes clear she has no intention to. She also doesn't want anyone that the Cuckoos can manipulate and turn against her. Once over the warehouse Laura has Warren release her. She crashes through the skylight, but too late.
The Cuckoos activate Dr. Marks' machine.
Another brilliant issue. After the much more character-driven issue 2, #3 drives the plot forward with action, beginning with the opening car chase, and ending with Laura's dramatic crash into the warehouse.
As with the previous issues, the Cabal/Woodward team is the glue that holds the book together. Cabal's spectacular use of panels and layouts keeps every page interesting and dynamic, greatly supported by Woodward's colors. And of course there's more gags to be found (Laura's phone, once again).
We also get a hint as to Laura's reasoning for returning to the X-23 moniker. While not everyone will be satisfied, at the very least the book acknowledges that Laura hates the name. However she's resumed using it for a purpose: With her new self-appointed mission of putting down people like those who experimented on her and her sisters, she wants her targets to know WHY she's coming for them. Hopefully we get more expansion on this in the future, but at the very least it's an explanation that makes a degree of sense.
Warren's cameo was a mild disappointment. As flying taxis go he WAS the most practical choice for Laura needing to get somewhere in a hurry, but the structure of this story would have made an awesome setup for a Mercury Falling nod and a Hellion reunion. At the very least, the appearance seems to confirm (while STILL not outright stating it) that Laura and Warren are no longer together. It also helps to place the series; Clearly it's set sometime before Extermination since Warren still has his energy wings (and, frankly, is still HERE).
But that's a minor quibble, as it keeps the issue moving quickly, especially after the criticism that #2 slowed things down a little too much. Overall it's a spectacular issue, and X-23 continues to be probably the best book in the X-line.
