It's a good thing John's as fast as he is, because when Charlie freezes Arthur’s thumbs are poised to scrape back down his face and into easily accessible holes.

But being grabbed startles Arthur into a bark of alarm, and immediately his legs are almost pinwheels, kicking wildly as he strains against the tentacles, yanking with all his not-inconsiderable might.

"John, let me go!" The tentacles are strong but Arthur is constant, half-slipping his right arm out on a horrible angle. "I'm gonna fucking kill him!!"

And he yanks an arm up so he can bite John's tentacle to try and tear its grip off of him.
