Sgibson: Practically nothing that happened in this episode was a surprise, because those of us who read the spoilers have been expecting it for months. They're all dead. Deceased. Kaput. Quantum singularity worm food. They're nothing but now&mdash;in this timeline. But they're going to be saved later on, because the events of this episode can be undone by time travel. Splinter's murder will probably be avoided before it can ever happen. Even Prime and Subprime may be brought back.
