Prompt – "Is that flammable? "We're about to find out."
"Is that flammable?" George asked Fred, looking at the potion in his twin's hand.
"We're about to find out," grinned Fred. "You made sure everyone is out of the store, yeah?" He went to add the potion to a cauldron containing a black powder.
"Of course. It was just Ginny left to close the shop and I'm sure she would have flooed home straight away," assured George.
"What about Harry?" asked Fred.
"What about him?" asked George, confused.
"I saw him slip in about ten minutes before closing. Did he leave?" asked Fred.
George shrugged. "Dunno, didnt see him, did I? He must have, or at least, flooed home with Ginny. It's dinner time, Mum will want to fatten him up."
"We should probably check, though," suggested Fred.
"All right, but let's be quick, the fumes alone are quite strong," warned George.
"I'll add some protective charms, just in case," agreed Fred. He waved his wand around the room once George had left. He then followed his twin, checking all over the store, straightening a few items and checking the till was ready for the next day.
"All done?" asked George, as they began to head back to their workshop.
"Yep, we're good to go," said Fred, following him.
They were nearly at the door when George stopped; Fred nearly ran into his back.
"What the – "
"Ssh? Do you hear something?" asked George.
Fred waited and listened, his eyes growing large when he too, heard a noise. He pointed to a nearby cupboard and George nodded. Both men had their wands at the ready as George quickly opened the door.
"Oy, do you mind?"
"Point that thing somewhere else, George, Fred!"
George and Fred lowered their wands, too stunned to speak. They looked between their sister and their pseudo brother, who had their arms around each other, hairs tousled and were both wearing the same annoyed looks at them.
"How long have you been in here for?" asked Fred.
"Not long enough. Bugger off," warned Ginny.
"We were about to do some potion experiments for new fireworks," advised George, " and they could've been dangerous!"
"I think there are fireworks going on in here," teased Fred. "How long has this been going on for?" He looked between the two of them.
"Well, the temperature has certainly risen," chuckled George.
"That's not the only thing that has risen," smirked Fred, looking at Harry's pants.
Harry blushed furiously and adjusted himself.
"You have no sense of propriety," snarled Ginny. She grabbed Harry's hand and dragged him out and throughout the shop.
"Someone's been hanging around Hermione," teased Fred.
"Does Ron know he's not Harry's favourite Weasley anymore," called George.
Harry shot him a middle finger.
"I hope you blow your shop up," replied Ginny, slamming the door shut as she and Harry left.
George and Fred looked at each other and paled.
"Shit, the potion!"
