So, the first day of senior year, Diamond and Silver had a falling out. DT's tired but expected game of "let's laugh at the freaks" somehow escalated into "let's physically assault the smallest and least offensive freak while she's all alone", which was not within acceptable parameters. Next thing you know it's a full-on ramming match peppered with "who's sick of who's insubordination" and "who's not the boss of whom". Spoilers indicate that Silver's going to get knocked on her ass, but a clean break from a lifelong relationship gone stale is rarely, well, clean.
