Summary
In Harry's 3rd Year, three new teachers arrive, which includes a pair of strange sisters. They're old friends of the new DADA teacher, Prof. R.J. Lupin, because they are - his old teachers? What's more: Sirius Black is unconditionally trusted by those two - the first almost squeals at the mention of his name. Whereas, Snape is unknowingly breaking the second sister's heart.
