Familiar Face (Harry Potter Fanfic)

When Sirius invites himself over to the Granger place to do the Muggle thing as he puts it, Hermione is far from thrilled at the prospect of her mild-mannered dad meeting Sirius with his intense personality; she didn't realize there would be another reason they might clash upon meeting.

Disclaimer - I don't own Harry Potter. This is written for International Fanworks Day 2022 where the prompt is to do a rewrite of a previous IFD work, and for this one I chose the series Muggle(born) Moments with this one being a remix of the first in said series, A Familiar Face which involves Hermione's inviting Harry over and learning her parents bought her AtLA on DVD to which she responds by inviting more of her school mates over

How did I remix?

In my story, Hermione isn't comfortable inviting anybody over to the Granger household. I also picked a fandom that was actually around in 1994 - Doctor Who while incorporating some of my AU headcanon for the Granger family including Regulus being alive and well living as Mr. Granger while also incorporating the idea of Hermione having a sister (sister's in this). And yes. I went into this looking for something I could remix Regulus being super duper into Doctor Who only to end up with a very unexpected idea.
