The Room of Entitlement
Parvati and Padma Patil were on a double date with Seamus and Neville. They just got back from enjoying a round of butterbeer at Hogsmeade and they wanted to snuggle. In order to avoid the "investigative journalist" Colin Creepy, they went to the Room of Requirement. This was the first time Padma had seen this place and she demanded that Seamus give her lavish presents. Seamus offered her cartloads of precious gems, exotic creatures and vintage LPs, but she was having none of that. She wanted the really cute diadem, which was perched at the peak of Mount Pile of Stuff. Seamus spent nearly an hour climbing up to get it, which caused Parvati and Neville to get bored and leave. Then he tumbled all the way down, breaking most of his bones. Padma snatched the diadem out of his hand and put it on her head. She felt very regal and far above Seamus, the mere peasant. She used Fiendfyre on the kerosene archive and left the room. The room's contents, including Seamus, burned to a crisp.
So sad.
