If the school does decide to suspend you, be proactive about reaching out to Hill and explaining the situation. It might also be a good idea to ask the principal or whoever was in charge of handling the situation to write a letter corroborating your side of the story.
I really hope your school recognizes that you’re not at fault and it never has to become an issue. Unfortunately these things can get ugly for both sides when there is any sort of physical altercation involved. Ugh I’m sorry this is happening to you.
Have a worst case scenario plan, but like others have said there’s no sense in worrying before you know how your current school is going to respond.
