The moment was HEREEE!
''Expecto Patronum!'' Cue the circular movement of the wand annnnd his focus on the memory of him and AJ sitting on that Bridge just over two years ago. Fixing his specs more comfortably on the bridge of his nose, he eyed the Hippogriff feathered core wand tip. Not so much of a wisp of... anything had made itself known. No worries! Adi did know that the spell was a VERY complicated one. He would simply try again.
Too excited to sit the way he was currently position, Adi rearranged himself so that he was sitting on his feet.
"Expecto Patronum!'' Concentration on happy memory? Check! Wand movement? Check! Something emitting from his wand? Nope!
"Going to make something happen soon.'' He shook his wand as though it were defective and the shake would fix it. Hehe.
''Expecto Patronum!" HEYO! Was that a puff of something?!
Or had he imagined it? Noooo, don't let it be his imagination!
