(Merlin puts the dragon's egg in the safety of his backpack as the tomb of Ashkanar collapses, right before Arthur and the knights arrive.)
Arthur: What the hell happened?
Merlin: The tomb was a trap. He set it off. He never got out.
Arthur: What about the egg?
Merlin: (Shrugs) It would've perished with him.
Arthur: Are you sure? We need to be certain!
Sir Leon: Nothing's going to survive under all that.
