Hwy FJ, I'm Tara, the second half of the modly team here :)
I have three babies here right now, firstly, this guy, Mr Harry Potter! As discussed, he's excited to have the second third of the trio here with him, and loves Hermione like a sister. And yanno, still completely relies on her for anything magical and complicated.
Secondly, I have Hestia Jones, who's pretty important in the DMLE, so Hermione might know her from the ministry, but she's a few years older than the trio, so I doubt she'd know her beyond that.
And lastly, I have Stephen Cornfoot, who was trio-age in school, but in Ravenclaw :) Maybe they'd be acquaintances?
Anyway, feel free to grab me on AIM or email for plottage! It's good to have you here :)
