Julius shuffled a bit when Matt poked him, grumbling at the name and trying (though not very hard) to get out of his cousin's reach. "'m no' lazy," he insisted, his speech a little slower, more deliberate. "Done more work in a week than you in a month." He didn't mean offense by the words, of course- and if he were more coherent he likely wouldn't have said them at all.
When Penny spoke up, Julius shifted, squinting until his eyes focused on her- but she wasn't Genevieve, so instead of walking away (or trying to), he just rolled over and pulled his pillow over his head so as to pretend they weren't there. "'m fine."
