Most people would agree that in a higher dimension, one is allowed to see an extra side of a lower dimensional object.
Fred, being a 2 dimensional being things he is closed all both sides. Bob of course can see an extra side of him which isn't covered. He can see his inner organs, blood and brain. Fred's internal organs are supported upright by the boundaries of his dimension. If Fred ever decided to leave, it would spell death for him. Bob mistakenly pulls Fred out for the first time. Now his internal organs are no longer supported by his dimension anymore. Lacking Z value, they immediately fall out left or right, killing him.
The same could be said for Bob, he thinks he's fully closed. But to Emily, he's exposed. She pulls him out, and the same thing would happen.
Could this possibly happen?
