Pissy?! If Rose hadn't already been highly annoyed at her brother, that word alone would've had her spitting. PISSY!
"I don't need this, Hugo. Leave." Her voice had never been so cold. It was as if panic had gripped her, her heart thudding so hard and fast it was starting to hurt. She hated her brother. That was... an unknown emotion to Rose who had, of course, hated some people in her life. But never her brother. Her precious baby brother she had always loved. Until now. "Get the hell out."
