"I've tried that," Sky said, staring at the floor. "In my darkest times I nearly starved myself to death, a friend of mine who could heal some of the worst injuries I've ever seen tried to remove the toxin. It didn't work...The only reason I have lasted this long is through sheer force of will stopping it overcoming my immune system. Hero-killer weapons earned that name for a reason."<br/><br/>"But Aniko could heal herself," Clint said. "I used to have her powers memorised, how would it kill her?"<br/><br/>"Aniko's power was regeneration," Yuri replied. "What should have saved her life doomed her, she couldn't slow her regeneration and every time she regenerated the toxin spread further. She survived one of the worst earthquakes in Japan and yet it took one toxin riddled bullet to bring her down. THAT is why Carreyra is dangerous, he deals in weapons like that."
