What is it?' asked Stuart.

He and Sarah Jane studied Mr Smith's screen.

'Dark Horde. Again.'

Sarah Jane sighed, but Stuart caught the glimmer of concern in her eyes.

'You took them out before, didn't you?'

For a moment, she hesitated.

'Yes, but with help, from an…outsider,' Sarah Jane said, sitting on the attic step.

'Oh?'

Stuart folded his arms, but Sarah Jane was unyielding.

'Someone like me? An alien?'

Long pause, then another sigh.

'Ruby White. She was a Qetesh - a soul stealer. Clyde and I were only just lucky the last time.'

A montage of her ordeal replayed in her mind. She simply shuddered - the giant stomach, the chains, forgetting the Doctor's name. Horrible.

Despite his few hundred years of being, this was a species Stuart had never heard of, let alone encountered.

'And you think she might be behind this?'

Sarah Jane stood up. 'Oh, no doubt about it.'

Stuart glanced at the screen, chuckling.

'Talk about a one-trick pony. Then again, we could see what she wants. Probably not a simple revenge plan, eh?'

Sarah Jane flashed him a look which dripped with apprehension.

'What about Clyde and-'

'Nope.'

Sarah Jane studied the hard stare in his eyes, sighing. She knew when she was defeated.

'All right.'

She grabbed her jacket and sonic, and they left.
