Okay, kids. This is Lettie with Marnie -- who is Darwin Baddock's half-sister, although she's not really aware of it (and not only because she's a little ditzy).

She helps Estella teach dance and she is a muggleborn. Also -- she's in Grayson/Rabastan/Noah/etc's graduating year, so plots are welcome!

Friends/enemies/awkward-sex-partners?

She's bendy. ;D
