In Hogwarts Mystery, Penny tells the MC that Snape is nice about letting her take extra ingredients to brew her own potions and she even says “I actually think Professor Snape quite likes most of the students. He just has a funny way of showing it”. I find it very interesting that the creators decided to include this. While most of the student body doesn’t like Snape, not every student had the same experience with him. Snape may not have wanted to be a teacher, but it is possible that he would appreciate students like Penny who took a special interest in potions just as he did when he attended Hogwarts. It is noteworthy that Penny is a Hufflepuff and perhaps her compassionate nature is why she is able to speak kindly of Snape unlike the majority of the students. Maybe I’m alone in my thoughts, but if a well-behaved child approached Snape and asked to pursue potions outside of class, I can’t see him turning them away. If he could sense that they were truly enthusiastic about potions and that they had no bad intentions, he might very well provide them with the necessary tools to nurture their gift.
