It's all over now. There is nothing to do and no way to live. Several universes are lined up in some kind of dark area where nothing else exists. They used to just sit here with no connection, but now that somebody has jumped from time to time, creating new parts of a universe inside another, they are linked.
The timelines have taken their path through one universe to another. Everything is now dependent on its neighbor to exist.
But this realm is being destroyed. The reality of space has been torn apart and is no longer stable. The Universe begins to glow red and shrink into its death with a horrible squealing sound.
Now I am sure everything is done for. Every piece of existence is connected. When The Universe collapses, every universe tied to it will shrivel up and die in sequence.
