I would agree, except 2 things make me think this is not a "slam dunk" type answer.

1) - Why did the shed stick in that spot in the first place? I know, it happens, but if the rest of the shed came off, why not that spot? The edges are very sharply defined, not ragged like the edges of the little bits of stuck shed my snakes sometimes have. Was the rest of the shed in one piece? If so, that would make me even more concerned about why this spot stuck.

2) - The OP says that the shed on that area came off "very easily" with some warm water. I would not expect that would result in pulling off such a large area of the underlying layer. Of course, different people would have different definitions of what coming off very easily means, so that might be part of it.

I would double check everything in the enclosure to make sure there is not any place where the snake could get burned or otherwise injured. If not, then it is probably ok to just watch that area very closely to see what happens.
