No no..
She gets up, and dust her dress off.
"I 'm alright, I assure you. Don't bother Dr Salik with something as trivial as my crashing into solid metal.."
She looks down at what Mark is holding in his hand.
"However, I do still have one good arm left to swipe the thread back off you."
She lunges at him and grabs the thread...but Mark tugs back with one end still in his hand.
Her eyes narrow at him.
"Ohhh, I see. It's like that, is it? You want to lay tug o war, huh? Very well, so be it..."
She puts all her strength into her good arm, and gives a ferocious pull at the thread, until it finally gives way.
Mark stumbles backwards, dazed.
Ha haaa! Tis mine! , she says smiling sweetly.
