Nagini could spend far less time with Voldemort than in her first year. He was now a prefect and had many extra duties on top of his homework. They both had time turners because of the amount of classes they took, but Voldemort refused to use it except for extra homework time and his own research time rather than leisure. Every once in a while he allowed her to follow him around invisible but it was still minimal time.
She relished every moment she spent with him, hiding stray feelings. She wondered whether he was in her mind at this very moment, processing her thoughts or confusing her further
Today was one of those rare days that they could spend long amounts of time together. Voldemort had snuck quite a few more horcrux books into the Room of Requirements and they were reading through, trying to take out any information hidden on those pages. It seemed like none of the books would give them a full account on how to create one.
This is hopeless, Nagini was thinking. It's no wonder he never found out how even after all these years. All most of these say is just that you need to kill to split your soul and then encase that portion in an object, nothing else. Nagini withheld a sigh and closed her 2nd book of the night. The entire book was about Horcruxes, and it still gave minimal information about how to make them. Half of it was actually about wizards who actually made them, or suspected to anyways. There was actually a section that proposed that the reason Grindelwald hadn't been killed yet was because of his horcruxes.
They were actually right next to each other, so if one found any relevant information, they could show the other without having to shout across the room. Nagini took another book out of the pile and began reading again
"Horcruxes, one of the most evile and wicked inventions created by wizarding kind, focuses on ripping one's soul in the process of killing and encasing it in an object outside one's body….."
Nagini could feel herself becoming drowsier by the minute, rereading sentences without taking in information until her eyes finally shut and her head fell onto Voldemort's shoulder.
He allowed her to do so until he finished his own book and then prodded her awake and they headed up to bed together.
