"Doctor!" Jack called out sharply and slid himself forward, inching himself as close as he could without being consumed by the mud himself.

"Oh no you don't," he shouted at the creature and reached one arm out for the tentacle, desperately trying to dislodge it from him. "Just look at me, Doctor," Jack said to him, trying to calm him so the creature didn't overcome him. "I'm not losing you, okay? I'm not losing you like this."

He kept a hand tight around the Doctor's arm, tugging against the pull of the creature. "Doctor, I'll get you out, I promise. Just trust me, okay? I will get you out. Now relax, the more you struggle the more these things win. If you relax it'll think it's got you so it'll ease off."
