In the He-Man episode "The Cat and the Spider" there's a very odd second of animation during the final climatic battle with the demonic Grimalkin. Just as He-Man asks, "What does it take to stop that thing?" we see Kittrina move next to him, as if she's about to say something. In the actual script she replies directly to He-Man, "It can't be stopped." Obviously this piece of dialogue was very close to being in the final shot, but cut for time reasons.
