Okay, I know this was somewhere in the 5th book but for some reason, I just can't find it. I don't know if I can post this since it's in the book but I just couldn't find it, but I'll still give it a try.
So, in Order of the Phoenix, it's mentioned (at the end of the book) that Hermione now has a scar because of Dolohov's spell. In the book it says the spell passed through her chest like a whip, so I'd say the scar is on her chest, but I've read some fics where it's on her stomach and I honestly don't know where it is.
I don't know if we need a reason to post this, but I'll give one anyway: on a chapter of my WIP, Hermione doesn't have a shirt on (since she's in a beach and everything) and so I need to know. Help, anyone? :)
At first I didn't really think about the 'whip passing through her chest' part but as I was writing the post it came to my mind. So sorry if I confused anyone.
