It wasn't a Deathly Hallows one but I used to know someone with a Harry Potter tattoo who got it altered after J K Rowling started going completely off the chain and while I obviously commend him for doing it he got it done at a tattoo place that specialised in changing/covering unwanted tattoos that tended to be frequented by people having gang or EDL tattoos fixed and it's kinda hilarious to imagine a Harry Potter adult in the waiting room with them all lmao
