A deceptive quiet hangs over the X-tale home. I watch, taking it in: Cross, a pillar of dark bone and intent, stands at the kitchen counter. The methodical *scrape-scrape-scrape* of a blade on stone fills the space. On the couch, X-Chara lies curled, pale feet tucked under him, his entire world narrowed to the glowing screen in his hands. The air between them thrums with a sibling rivalry so old it's become a language—sharp, possessive, and, to my eyes, strangely endearing on this still afternoon.
