Dominic and OPEN to MULTIPLES
Every single type of meat imaginable was on Dom's plate, not to mention the potatoes, of various sorts, all drowned in gravy and vegetables as he told stories of the summer, laughing with varying sorts of friends and joking with them. Occasionally stealing something off someone's plate, though it wasn't necessary, or dumping something unappealing onto another's plate. It was always in good fun, and Dom tended to like being the life of a party.
Anytime one of the first years got announced as a Gryffindor, he'd let out a roaring, loud shout of excitement. Probably a bit over the top, and probably just a bit sarcastic, though he tended to like most everyone in the beginning. Until you ended up pissing him off. Also, house pride and all that.
Dressed in the robes and uniform of the school, Dom felt entirely at home in them, and at the same absurdly annoyed by them. "I sweat, Seventh Years should be wearing whatever they want, it's our privilege now. Being the eldest, the wisest, and in some cases, the best looking..."
He took a roll and launched it across the tables at the back of a Slytherin's head, winking at them before looking back to people, "I missed school. It's like a Warzone and Play Place all in one... where everyone loves to hate one another."
