It was hard to explain just how horrible Parvati felt. She was a pureblooded witch, and prided herself highly on that. It was her magic that gave her strength and conviction. And now it was gone.
On top of this, there was a fear. She knew Draco loved her, but her fear was of the Malfoy part of him. The part that hated Muggles and anything spawned from then. The part that would never knowingly take a squib for a wife. And that's what she was now, wasn't she?
When no other words came out from her husband, Parvati sobbed harder, "Okay? Okay what? Draco I'm a squib! I'm nothing!" She was a mix between anger and misery. If her magic had been intact this would've been when her emotions would've caused a sparking nearby, she was so distraught. As it was however, nothing happened.
