Cracked Mirror

The Protostar proto-jumps to Voyager's position but arrives in the wrong reality, one where Janeway and Noum died trying to rescue Chakotay, and then in another where the living construct destroyed the Federation. The crew realises that the jump has torn the already weakened fabric of the universe, splintering Voyager across many realities, and the strain is taking a toll on Gwyn. Rok and Zero become trapped on a Voyager commanded by Tuvix, while the others, apart from Maj'el, who is accidentally left behind, land in the Mirror Universe and come face to face with brutal versions of Janeway and Chakotay. With the Loom threatening her own universe too, the Mirror Janeway reluctantly lets them use her ship to emit a pulse that closes the rift. Arriving at last on the right Voyager, Chakotay is finally reunited with Janeway.
