"A loud bang echoes around the stadium and a jet of green light shot out of the wrong end of Ron's wand, hitting him in the stomach and sending him reeling backwards onto the grass.
'Ron! Ron! Are you all right?' squealed Hermione.
Ron opened his mouth to speak, but no words came out. Instead he agve an almighty blench and several slugs dribbled out of his mouth onto his lap."
Well, that plan backfired...quite literally. Somehow managing to hide your dusgust, you and Hermione lead Ron away and towards Hagrid's hut, he'll know what to do. You hope.
Better out than in!
It seems like the only way to make this stop is to way it out. Poor Ron. By the time his slug vomiting interval has decreased to every 20 minutes or so, it was time to head back to the castle for dinner.
'You guys go ahead, I'm not feeling particularly hungry' Ron said. His face was a shade of sickly pale green as you led him back to the Gryffindor Common Room.
