Potions was Hadrian's first class when he got back.
Tom looked at him in concern when he noticed the raven haired boy angrily throwing random ingredients into the cauldron and fiddling with the temperature while stirring occasionally.
Snape noticed that Hadrian was not following any of the instructions on the board and was going to say something when suddenly Hadrian's brilliant Avada Kedavra green eyes glared at him murderously, almost daring him to say something. The greasy haired man opened his mouth before the magic hit him and he shivered as if drenched with an ice cold bucket of water and then left outside in winter. He turned around to yell at somebody else.
Tom was extremely concerned now and barely noticed when Hadrian's cauldron had turned crystal clear and a mini explosion was heard causing everyone in the class to jump.
"A couple more stirs and then I can have revenge." Tom barely heard Hadrian mutter. Everyone stared as Hadrian bottled his potion up after ten minutes and left the room with it.
