1 year later….
Nagini was in the girl's bathroom. Her eyes brush past the sink and she sees one of the taps, with a snake engraved in it. She quickly rinses her hands and runs all the way down to the common room.
"Voldemort!" she gasps.
"What?" he asked, looking concerned.
"I think I just found it," she pants, "In the girl's bathroom."
She opens her mind to him and shows him a picture of the tap and the small snake.
"Come on," he says, attempting to drag Nagini with him. She withheld a chuckle, thinking that he was acting like a child.
But she said "Just a second, let me rest for a second."
He points his wand at her and for a minute she thought he was going to curse her, but she suddenly feels energetic and follows him up to the bathroom.
"Are you sure you want to enter a girls' bathroom?" she giggled.
He shot her a dirty look and said "You check if anyone's in there."
"Aye," she responds and goes in. A few seconds later, a young Hufflepuff runs out sobbing. Nagini follows. "Coast clear," she reports, giving him a small smile.
He enters and walks straight to the sink and inspects the small snake. "How will you open it?" she asked. He doesn't respond, but begins tapping the tap with his wand. Nagini uses magic to feel her way around the tap, trying to look for clues, until Voldemort snaps, "Stop it, you're confusing me."
"Well, I found something, but you're obviously clever enough to find out by yourself," she smirked.
"What?" he asked, then waved his wand.
"This opens up to a large pipe."
He hissed a single syllable and immediately, the tap glowed with bright white light, and started spinning. The sink then began to move and sank into the ground, exposing a large pipe, large enough for a man to fit into.
"Parseltongue," he explained. "Can you light this up?"
Suddenly, the pipe was filled with greenish light but all they could see was a twist. "Who's going first?" she asked nervously.
Voldemort sighed, "Fine." He sat down on the edge and slid forward. She could hear him slide down and she quickly followed suit. The pipe was extremely dank and slimy. It seemed practically endless and she could see smaller pipes branch off from it. But finally, she heard Voldemort thud as he finally hit the ground. Soon after, she shot out the end, landing on the damp floor. Behind her, the pipe darkened. Voldemort lit his wand, and finally, Nagini's managed to do the same. They made their way down the tunnel and its many twists and turns until finally they met a solid wall with two stone snakes entwined with emerald eyes.
Voldemort gave another strangled hiss and the wall cracked open, to a large chamber held up with stone columns entwined by more serpents. It was dimly lit with a faint greenish glow. At the end, a large statue was in place, of no other than the great Salazar Slytherin himself.
Nagini found herself trembling when she looked at the scene, while she could see that red gleam in Voldemort's eyes. They had finally found the Chamber of Secrets.
Voldemort suddenly turned around and kissed her full on the mouth briefly. A faint pinkish tinge appeared in his cheeks after he did so and they were silent for an awkward minute. Voldemort recovered first. He gave her a wide smile and she could see a look of utmost happiness on his face, an expression that seemed to distort his handsome features into something inhuman. "I placed my faith on the right person," he said. "Nagini, you're absolutely wonderful."
She didn't know how she was supposed to answer that, and could only blush and look like an idiot. He smiled knowingly and looked back at the statue of Slytherin. "Call the monster out," she told him.
And he turned around to face the statue.
