Hermione startled at the sound of the door opening, indicating the library had visitors. They hadn't yet been paid a visit by any of Marrowood's more... unsavoury residents, thank Merlin, but that didn't mean they couldn't enter. So she drew her wand, unwilling to take chances when Ginny Weasley's pseudo-lifeless body lay nearby, under guard, and stepped towards the door, into the foyer.
She didn't recognise the man and woman who had appeared, but it was impossible to miss the arsenal they'd brought with them. In comparison, Hermione felt rather ridiculous simply holding her wand, but it'd worked wonders for her before. Marrowood's strange effects on her magic aside, she hoped she could hold her own.
"You're here to help?" It was partly a question, yes, but more of a statement all the same.
