Commander Chakotay (Robert Beltran) is rendered unconscious by a temporal energy blast from the warp core. Upon awakening, Chakotay finds that the Voyager has been "time-zoned," half of the ship is in the past, and half is in the future. In addition to offering a fascinating crash course in Voyager's history (with the help of a few judicious chosen clips from earlier episodes), this episode also marks a return appearance by Dr. Chaotica (Martin Rayner), the central character in the Doctor's (Robert Picardo) holographic novel. "Shattered" was first telecast on January 17, 2001. ~ Hal Erickson, All Movie Guide
