The sound of the shattering glass made Martha turn on her heel to see what had happened to Severus, and she'd opened her mouth to say something. A quick teasing comment, perhaps something about not holding his drink but the sparkle in her eyes died before the words could pass her lips. His expression, watching the shock play out in it, made her worry and it showed on her face.

The hand on his arm left the reason for what had happened easy to identify, and Martha quickly moved over to his side, touching the hand that was clasped over it.

"He doesn't know you're here, even if he is. Maybe he isn't...." She was trying to be hopeful, but she was aware of the fact that if Voldemort was here, and he was from after his death, the amount of danger in their lives had just risen exponentially.
