With Isabelle's heels clacking and Magnus' glitter sparkling, the pair walked out the Institute's complicated door together with wallets ready. Magnus had come to pick up Isabelle for their weekly shopping trip and tell Alec he loved him. Alec had just seen the two to the door when Simon clambered down the large steps to Alec's side.
"Hello, Alec, how are you today?" Simon said cheerfully.
"Hey."
"You actually decide to converse with me for once. Are you feeling okay?"
"Perfectly fine actually. Do you think that Magnus and Isabelle are going behind our backs?"
"Wait, what? No, why would you think that?" Simon looked at Alec with incredulity. Then Simon smirked. "Well, if they're going behind our backs, why don't we go behind theirs'?"
That conversation ended with a bloody nose and a bruised eye. You can probably guess who was on the receiving end.
