"I'm sorry," Draco gasped and staggered for the door, just making it out and slamming it shut behind him before a heaving spasm grabbed him and shook him. The corner of the cellar was right there, two steps away, and Draco stumbled to it and vomited all over the packed dirt floor, shoulder leaning heavily into the wall as he bent nearly double, emptying his stomach violently. He choked and retched, fingers scrabbling at the wall to keep himself upright as his eyes streamed and his stomach emptied itself over and over, until all that was left was acid bile that scorched his throat. Draco's abdomen ached from the spasms, his throat burnt, his mouth tasted sour and rancid, and his face was salty wet when the wracking heaves finally stopped.
