Nagini woke up the next morning in the common room with Voldemort sitting across from her, reading a large, blank black book.
"You know," he began, "I thought you nearly died last night."
"I didn't know how much energy it was going to take," she said in a small voice, scared that he might be angry. "And I warned you about lugging me back."
"Fair, but really…By the way, your sculpture still stands. I believe quite a few students are looking at it at this very moment.
"Good thing it's the weekend, it's nearly noon now."
She smiled, "So how'd you like it?"
"Heh, it was magnificent. But why did you faint like that?"
"Think of it as the only defect in my skill. The harder something is, the more magic it takes me to accomplish it, the magic coming from my own body. It used to be awful; I could barely raise a few coins. Apparently it gets less tiring as my magic improves."
He toyed around with this concept. To him, magic was simple and seemed absolutely effortless. However, it was obvious how much more freedom he could gain without the aid of the wand. Without a wand, it was obviously much harder to restrain, which was perhaps why Nagini became so exhausted afterwards.
"I think you're ready to meet the rest of my friends," he said, with a sly smile after a few minutes of silence. This was his first real test against her confidence and leadership qualities. Her power was unquestionable, but she seemed very…shy and secluded to him. Of course, those were fine qualities for servants; however, as she was a witch, it would be far harder to get the older boys to accept her into their ranks. Her talents lied in very slyness and possibly manipulation, but it was not enough.
Voldemort at this stage wasn't a fully accomplished Legillimens just yet, even if he could sense very vague thoughts and emotions. It would take quite a few years and currently, Nagini's mind was cold and secluded. He could sense nothing more than emotions, and sometimes, not even that at times.
It was that reason that he trusted her with his secrets. He knew she probably wouldn't spill them and it would be hard to take them from her mind.
She didn't know all this, thinking this was simply more acceptance.
