Lots of people have spoken of their appreciation for the alternate realities that we glimpse at the end, so I'd like to instead draw attention to the interludes featuring various characters in different locations responding to the "holes in space". Given my love for continuity - not just references to previous stories or established "facts" but the act of stringing stories and events into a coherent whole - I really liked these glimpses into other peoples' lives. Catching up with Klag and Shelby, seeing Titan exploring the Gum Nebula, getting a sense of how the economic situation is in near-Dominion space, and above all giving us some insight into the changing situation in Romulan space, helping link The Red King to the formation of the Imperial Romulan State at the end of Articles of the Federation. All good stuff. KRAD even worked in a reference to the loss of his Malon super-tanker in Demons of Air and Darkness.
