From Hermione
Fred and George heard a nasty rumor. Har, no- I mean Hermione and I? Dating? I think that Ron started it: every time I ask Harry about the details of the spell or have an idea for reversing it, he casts dark looks at us. If looks could kill, both my body, and the one I'm in would be on their deathbeds.
Dumbldore arranged a spell for us to be able to change each other without, er, revealing anything. Until the switch spell is off, no one can see either of us completely undressed. (I can see my body, not Harry's and vice verso.) It's already October and nothing's being done! Sometimes I look at Harry in the mirror and think that things would be easier if we got married…then realize what I'm imagining and wake from my daze.
