For a moment, Martha didn't know what to say. In the back of her mind she heard herself telling the Doctor that one should never meet your heroes. Severus Snape had never been her hero, not really, but as someone who always wanted to help broken creatures, he'd been her favorite. It felt weird to be in front of him now, gaping like some sort of fish or a teenage girl meeting a member of One Direction! No, she needed to keep it cool.

And more than that, he needed to know what it was that had caused her to act like a large idiot! As he started to withdraw his hand, Martha reached out and caught it, holding onto it without a bit of shame. Being here at this party didn't seem like the place to have the conversation with it's slumber party theme, and given how many of them happened to be here, Martha was betting that most other places happened to be rather vacant.

"Follow me," she said softly but calmly over her shoulder, giving him one of her best reassuring smiles. "It's probably better explained somewhere more adult, I think." Which almost everywhere was, Martha thought.
