Never in his life did Regulus ever think that he’d associate himself with a muggle born yet here he was with you. Obviously he wasn’t very open with hanging out with you in public to protect his reputation but when it was just you he was alright with that.

Regulus had snuck into your dorm using his animagus form. You had gotten bored so you decided to show him a bit of muggle culture. He was absolutely flabbergasted with some of the things you showed him. How they didn’t work with magic. You had taken a photo of him with a Polaroid camera and at first it was just a black square. Then Regulus saw you shake it and an image of him started to form on it and he was taken aback. It was so surprising to him that he took the camera and started inspecting the contraption.

“What kind of foolery is this…?” Regulus question turning the thing over and upside down trying to figure it out like a curious cat. At one point he accidentally hit the button that triggered it and the camera flashed in his eyes making him drop it.
