The beauty of a Howler, one could argue, was the surprise element.
Solomon had expected retaliation for his actions at the Slug Club Party for quite some time now, but all he got from the Flints so far was radio silence. No word of disapproval, not even in passing. As the days slowly passed, suspicion gave place to relief, and he allowed himself to relax, thinking that maybe not even acknowledging him was their way of showing contempt, their way of saying again and again: you're not one of us. He couldn't be more wrong. Solomon may have been on a warpath lately, but if anyone in the family was well versed in the art of war, that someone was the old matriarch, Mabel Flint. No one could quite hold a grudge like Mabel - and all Solomon knew of cruelty, he'd learned from her cold, silent anger, and her ring-heavy hands. She knew how to bid her time, to give him a false sense of security.
He didn't expect the bright red letter when the owls came in during breakfast - but once he'd realized what he had in hands, it was already too late. Her voice boomed from the parchment, filling the Great Hall with a rising wave of insults - "YOU TRAITOROUS LITTLE DEGENERATE! HOW DARE YOU SHAME THE FAMILY THAT HAS GIVEN YOU A ROOF, THAT HAS FED YOU, UNDER NO OBLIGATION EXCEPT THAT OF NOBLE SELFLESSNESS?" Solomon wished he could fight the goddamn letter, but he knew that would be of no use - all he could do was wait for it to die down, and let Mabel have her little revenge. He supposed he deserved that, after his altercation with the Minister, but it still stung. "YOU ARE NOTHING BUT AN UNGRATEFUL SERVANT, BRINGING SHAME TO OUR FAMILY AND YOUR OWN - HAVE YOU NO OUNCE OF RESPECT FOR YOUR POOR LATE MOTHER? FOR YOURSELF?" He kept a smile on his lips as she went on and on, but it never quite reached his eyes - Solo was no stranger to shame, but he couldn't just let the Flints win. "DO YOU EXPECT TO LIVE ON CHARITY FOREVER? PUT YOURSELF BACK IN YOUR PLACE OR WE SHALL DO IT."
She kept going for a while - a string of loud, elegant cussing, and a small don't forget we love you, Theodore, take care for his cousin - and then it was done. Silence rang on his ears. He refused to leave the table, despite the pounding on his chest, taking a bow instead. "Alright, show's over, folks! Thank you for tuning in this episode of Family Matters!" And if his voice trembled a little, no one could really blame him, could they?
