Trelane, who first appeared in the original "Star Trek" episode "The Squire of Gothos", is revealed to be a member of the Q Continuum. He taps into the power of the continuum and uses this ability to tamper with time and reality, resulting in the intersection of three different parallel universes which are also referred to as time "tracks". Track A is a universe in which Beverly Crusher's husband Jack never died, and now serves as captain of the "Enterprise" with Jean-Luc Picard as his first officer; in this universe, Jack's son Wesley died as a boy and Jack and Beverly divorced. Track B is the traditional universe depicted on "Star Trek: The Next Generation". Track C is akin to the more militaristic alternate universe shown in the "Next Generation" episode "Yesterday's Enterprise", in which the Federation is at war with the Klingons.
