Although he was extremely concerned when Rose Potter and Ginny Weasley were sorted into Ravenclaw instead of Gryffindor along with Astoria Greengrass. The younger sister to The Riddle’s friend Daphne, that connection was enough to start up a friendship. He had seen the three first years join the Slytherins in the library, at the courtyard and even down by the lake. He didn’t like them bonding, he wasn’t sure what it was that made him uncomfortable beyond that they were Voldemort’s children, it was something else that nagged at him. But he ignored it and forced himself to relax and replan. Hopefully, he could use that friendship to sway Hartford and Hermione when the time came. It wasn’t like Voldemort would spare the sister of the boy-Who-Lived or the daughter of the pureblood blood traitors. He also didn’t like the friendship that appeared to be growing between Neville Longbottom and the eight Slytherins. Severus had admitted he paired Neville with Hartford in the hopes of "preventing Longbottom from killing his classmates in potions.’ But he was wary of it going further than just tutoring friendship. He couldn’t have any of them figuring out what he had done, and he had future plans for Longbottom, he would not let anyone ruin them.
