An elephant approaches the event horizon of a black hole, you as an observer watch from a safe distance (for the sake of discussion, we'll say 1 light-second away). We see it slow as it approaches the event horizon, but never actually see it cross, however nothing ever escapes a black hole (except possibly as Hawking radiation).
Question, if we see the Elephant still slowly approaching the event horizon, but the elephant has indeed crossed it, is the elephant in two places at once, or is the light from said elephant hampered by the gravitational field of the black hole, slowing it down say, to make it appear like the elephant never breaches the event horizon?

On my opinion if the elephant does not cross the event horizon than we can see him with delay depend on distance (as you mentioned 1 light second).
But if he passed the event horizon than we will see nothing because of nothing can return from black hole.
