Theo was a dick, and he didn't even try to deny it, but he wasn't going to ignore it when he saw the popular Slytherins harassing you again.

he stood behind one of them, Astoria, and grabbed her elbow, pulling her away from you as she insulted you again and threw your books out of your bag.

"You have two seconds to fuck off."

he said dispassionately, she looked at him askance but left with a bunch of her empty friends, his eyes went to your books and started to slowly pick them up.
