Entertain
Theodore Nott is not at Hogwarts for anyone's entertainment and everybody knows it.
He's always serious or scowling or yawning if he's not doing the aforementioned. His eyes had a gaze that would kill or at least maim if it were so possible and legal.
So why was everybody staring?
He lets you rush off to your friends and settles with his own.
"What?" he says to a staring Draco
"You're going soft"
Before he could retort, Pansy objects to the words - "I thought it was cute"
"He could just hold her hand!"
Oh. They were talking about the fact that he'd linked pinkies with you.
"She likes this better"
Mattheo snorts.
Theo doesn't mind; well aware that his friends would sooner gouge someone's eye out than hate on him.
He walks you to your next class with your pinkies linked.
