Spoilers: The Runaway Bride, The Fires Of Pompeii.
Summary: Donna tests her own mettle.

Marrying Lance had seemed like a triumph, until she’d learned the truth; he’d never loved her, and her self-confidence had suffered another body blow.
This was her acid test, here in Pompeii on Volcano Day. She had to stand up to the Doctor, make him listen to her.
