Charlotte didn't even hear Aaron's question as she already was playing around with the bullet. He fingernails could quickly extend into screwdrivers, that was only one of her abilities granted to her by her mechanical body. She was quickly going around the table picking up the materials she needed. And after no longer than twenty minutes she was done.
The inside of the bullet was considerably smaller than it was before but it would serve the purpose it needed to. The extra parts Charlotte added would generate a one time load of energy. Once it impacted on a living being it would send a shockwave through the nerves of that being that traveled all the way to brain, putting the target to sleep for the next ten hours or so.
"Can you reproduce this?" Charlotte asks Aaron innocently while holding out the bullet on her palm showing it to him.
