Ron glanced at Hermione, then said, “What if pure bloods and half-bloods swear a Muggle-born’s part of their family? I’ll tell everyone Hermione’s my cousin–”

Hermione covered Ron’s hand with hers and squeezed it. “Thank you, Ron, but I couldn’t let you–”

“You won’t have a choice,” said Ron fiercely, gripping her hand back. “I’ll teach you my family tree so you can answer questions on it.”

Hermione gave a shaky laugh.
