In the Chamber of Secrets, when Dobby first appears in Harry’s bedroom, Dobby tells Harry about how he has heard all about Harry’s greatness.
But if he serves the Malfoys and rarely leaves the Manor, who told Dobby these things?
My money is on Draco
I remember in year 2 there was a girl who had literally never had a haircut so her hair was ridiculously long [imagine Rapunzel basically] and she always complained about it but her mum wouldn’t let her get it cut
So one day at recess she put an entire pack of chewed gum in her hair at the exact length she wanted it cut to.
She came in the next day with her hair cut how she wanted it and a smug grin on her face and I knew that that girl was going places.
