You mean the Slytherin part? (I think my grammar is pretty on point. lol)
There are four houses for all Hogwarts students. Hermione is in the Gryffindor house (heroic do-gooders), and Slytherin is pretty much the evil-doer house out of all of Hogwarts. Those two houses are pretty much enemies, so it's weird that there's a green and white Slytherin scarf in the lower right corner right next to Hermione wearing her crimson and gold Gryffindor scarf as if the two are sitting next to each other. I think that's fairly unheard of in HP.
HTH
I feel like such a geek with all of that explanation....
