The one thing Miles is worried about - since he's almost positive that this thing is some manifestation of Josh's personal darkness or his ... fears - is the concern that their bodies might be physically linked somehow. Like he could wail on this thing with all the strength in his spiderfied body and it would somehow hurt his friend.

He's thrown some hard knees at the wendigo, though. His pal seems to be horrified, but not in pain - at least not that he can sense while he'd wrestling with this thing.

He can't get around to the creatures back. Miles tries and almost lost half of his face from a claw swipe. He gets it off balance. One of the next best things. The young spiderling goes low and throws a sweeping kick at its legs and then instantly springs backward with a shocking agility.
