Yoongi had seen the nod in his direction while Professor Flamsteed had been talking to Trixie. A newest addition to the Gryffindor team and also one of the food throwers. He would have refused offering help but the girl hadn’t thrown food at him. UNLIKE A FEW OTHERS. And he couldn’t refuse the Head of House now could he?

Face expressionless but his jaw clenched, Yoongi walked towards the two before standing beside them. “I heard you , Sir. I can help her out, I don’t think they deserves help but I will” Just a honest opinion of the Head Boy they had aimed for, had the man not seen that? oh no wait, he had been unconscious! Merlin's Beard....

He turned to Trixie, looking at her picking up food with her hands and resisted rolling his eyes. “I’ll teach you two spells that come in handy now, if you don't want my help say so now and i'll get Candice” he said without a smile but his tone was definitely softer now. He couldn't stay mad forever, he knew they were just having fun but that fun was at the cost of him and he would not forget that. "Take out your wand"

Ooooh House elves! Poor creatures. They had made this food with their hard work and it got ruined because SOME OF THEM decided to ‘have some fun’ ugh.
