headcanon that since the slytherin common room is under the lake there’s a room where the walls and ceiling are glass and you can just see into the lake like an aquarium
headcanon that when this was first done the mermaids got really aggressive and hateful about it and started ramming the glass but since it was magic this just caused them injuries
until a deaf/hoh slytherin started to teach them sign language and it took a long time bit by the time they left hogwarts they and the rest of the house were communicating with the mermaids and on good terms
eventually it becomes a part of slytherin house culture you’re a slytherin you know sign language because if you don’t chat with the mermaids they get grumpy
this helps a lot of deaf/hoh students
this also gives slytherin the best grades of any house on all aquatic magical studies
the mermaids give terrible dating advice do not trust them
The most common mermaid dating advice, of course, being “Drown him”
DO YOU EVER THINK ABOUT HOW DRACO MALFOY IS JUST A HUGE FUCKING MEME YOU CANT TELL ME HOGWARTS STUDENTS DIDNT SAY “my father will hear about this” OR “potter” ON A DAILY BASIS WHEN SOMETHING HAPPENED I JUST WONT ALLOW IT
I’m picturing instead of “thanks Obama” everyone just mutters “POTTER” every time something small goes wrong. Everyone loses their shit when Harry one day spills ink of himself and mutters “POTTER”
i still cannot believe they cut out “there’s no need to call me ‘sir’ professor” like…. everyone in the gryffindor class got that tattooed on them….. ron weasley literally had it put on his gravestone……. dean thomas literally almost made that entire phrase his first born’s middle name………. and ur just not going to put in the movie???
hp movie producers: the movies are strictly about Harry, this is his story hp movie producers: *ignore harry’s basic character traits*
