Following the raid on Cauldron west African base, Taylor was given more information on how second triggers worked and how powers changed and evolved. 
This leads Taylor to consider the idea of removing restrictions that help regulate powers in her brain, in the hopes of gaining an advantage in the fight against Zion. She asks Bonesaw for help, but Panacea decides to help instead, arguing she can do a cleaner job herself. 
As a result of the procedure Taylor's range of her power drops to 16 feet, but she gains ability to control the parahumans within that range. She loses the ability to vocally communicate, and as time goes on more and more of her personality becomes subsumed by her shard.
In the immediate aftermath Marquis tries to contain Taylor and send her away to a different world, until the time that the fight with Scion is complete. 
Taylor manages to break free and goes on to fight Scion and experiment with her powers using capes that fall under her control in the course of the fight.
She meets Glaistig Uaine and receives advice on practicing her capabilities,
and the necessity of choosing an anchor in the face of gaining power and losing identity. 
She begins targeting specific parahumans that are able to assist her task, starting with Doormaker and Clairvoyant, subsuming Teacher's students, the Yàngbǎn, and any still incarcerated prisoners in the Birdcage.
Looking through the available worlds she captures every available cape she can find. Including breaching into Supreme Earth and the capes there. The sole known exception was Sleeper. 
Finally she confronts and captures the group actively fighting Zion, starting with Glaistig Uaine and moving on to the rest of the defending force. 
↑“Second triggers are about knocking down walls,” I said. My eyes fell on Bonesaw. “Removing restrictions the entity put in place. If this part of the brain is a part that the entity shaped to help regulate powers on our end, then I need you to de-regulate.” - Excerpt from Venom 29.9
↑ “I’m inexperienced, yeah,” Panacea said. “But even inexperienced, I think I can do a cleaner job than you. And Tattletale’s less likely to catch on if you aren’t sawing Taylor’s skull open. - Excerpt from Venom 29.9
↑ “Sixteen feet,” Tattletale said, her voice quiet. “Fifteen point nine-eight feet, to be exact, but we can ballpark it.” - Excerpt from Speck 30.1
↑ “Ah,” Marquis said. “Shame. A communication problem makes it harder to gauge how much we can trust her.” -Excerpt from Speck 30.1
↑“Weaver is an unknown quantity. We’ll leave her here, as safe as anyone on any Earth is, and we conclude this fight against Scion, win or lose. When all’s said and done, we come back and we see what we can do for her.” - Excerpt from Speck 30.1
↑ “If you want to get a full understanding of your new capabilities, you must figure that out on your own,” she said. “Practice, and it will soon be second nature.” - Excerpt from Speck 30.2
↑ “You will need a tether, an anchor. It can be an idea, a physical thing, a place, a person, a goal. Right now, it will not seem so important, but it will. When all is said and done, you will either be dead, and this thing will be a comfort to you in your last moments, or you will be powerful, and it will be all you have left. Decide what you will hold on to.” -

↑ With my power, I seized control of Doormaker and the Clairvoyant. The pair stood, holding hands. - Excerpt from Speck 30.1
↑ Sleeper. I could see him, sitting on a lawn chair on a balcony, reading a book out loud to himself.
↑Then, group by group, I captured the rest of the defending force. Some resisted, some predicted the attack, but it was a foregone conclusion. I had enough soldiers, enough tools at my disposal, that nothing here really stood in my way. - Excerpt from Speck 30.4
