So back in school Parvati was pretty much as she was in canon - bffsies with Lavender, came across as a bit shallow, super into fashion and gossip and Divination and lots of things that Hermione hates XD She took a level in awesome after school, though; she now works as a Daily Prophet reporter, she cares much more openly and often about social causes, so I feel like she and Hermione might be closer as adults than they ever were when they actually lived together. (Though back in school Parvati definitely would've supported Hermione's house elf welfare stuff even if she didn't quite understand the point of it XD)
