Padma Patil
I swear to Merlin, I might actually go for House Bingo. Who needs a Hufflepuff line filled?
In the meantime, this is Padma! She's a Potions Mistress, and owns two apothecaries, aptly (and unorginally) titled Patil Apothecaries. One of them is in Hogsmeade, the other is Monument Alley. She's the quieter of the two siblings, way more reserved, but she's also open enough to be a succeessful businesswoman. Her Apothecaries specialise in Eastern/Middle Eastern potions, though Padma has stock of just about any potions ingredient. She leaves a lot of the 'traditional' potions to Adrian, and focuses on her specialty and selling supplies.
I am terrible at intros, so what else? She's very in-tune with her Hindu faith (both her parents are Punjabi Hindu, raised in India), though her father has disowned her (long story, but basically she rebelled against his strict classist/mysoginistic ways, including an arranged marriage - the app says Shafiq, but I'm willing to adjust if anyone wants to jump in on an arranged marriage), but that's probably not too public of knowledge. She has a white Siamese familiar, Shadow, who can be found sleeping in the window of the Monument Alley Apothecary most of the time.
She's a fan of the book corner at Finnigan's, though she doesn't drink alcohol. She also attends Battlescars regularly and LBB.
I think that's it! Her full bio is here so come at me with friends, apothecary customers, fellow book cornerers, LBB acquaintences, even enemies (but why would Padma have enemies?).
