It only reminded him that he didn’t fit in with those two, of course it could be that the friendship was fake, Dumbledore paid him to befriend Harry, but he never said anything about having to share him with... with some mudblood know-it-all! He wasn’t told that it would be the Golden Trio, not Duo, that Hermione didn’t have to be paid to be Harry’s friend, didn’t have to struggle to hide her jealousy, didn’t even have to try and Harry liked her! He had to work constantly to keep his head level and not snap at the messy haired git, gods Harry Potter was a prat! Pretending to hate his fame, acting all innocent "look at me, poor abused Potter’. He had a deal with Dumbledore and that was payment for befriending Harry, it was reporting on Harry to him, the Headmaster promised he’d become famous, the boy-who-live’s best mate, said he’d go on all the adventures, that he’d even be told what the adventure was beforehand so he could out shine the famous third year.
