Hon får ärr från Bellatrix Lestrange i bok 7 medan hon är fångad hos Malfoy.
I filmen sker detta i följande scen:
Enligt Harry Potter Wikia :
Hermione has Mudblood written on her arm, a cut on her neck and many bites, all of them made by Bellatrix Lestrange, in 1998, at the Malfoy Manor
Som kontrollerad i boken och även som kommenterad av Valorum:
Why shouldn’t I?” said Hermione. “Mudblood, and proud of it! I’ve got no higher position under this new order than you have, Griphook! It was me they chose to torture, back at the Malfoys!” As she spoke, she pulled aside the neck of the dressing gown to reveal the thin cut Bellatrix had made, scarlet against her throat.
