Brisco, meanwhile, is visited by "Karina", another time-traveler (like Bly) from the year 5502. People in her time built the three orbs ("to aid in the advancement of mankind"), but Bly (3000 years in her past) obtained them and ruled the world (in his time - still with me?) She tells him that Bly is about to be set free (from her point of view, this is all in the past.) If Brisco doesn't stop Bly, he'll steal them, return to his time, and begin his 2,000 year "reign of terror" over the world.
Pepe, having broken into the bank containing the orb, accidently releases Bly from the orb. When he turns over the orb to Agent Brown (who hopes to use the orb to rule the world), he is promptly killed for his trouble. Brown has the orb, and Bly is free, searching for it, as is Brisco (he hopes to beat Bly to the orb.)
Socrates Poole has been recruited by other government agents to be an "intelligence operative" for them (though he maintains his job at Westerfield as a cover). He is told of Agent Brown's evil intent, which he passes on to Brisco and Bowler.
Brisco is waylaid by one of Brown's underlings, but with Bowler overcomes him and learns of the orb's location. Brisco and Bowler confront Agent Brown, but in the confusion Bly steals the orb, so he can return to his time to rule the world.
Brisco, able to "feel" the orb's location, finds Bly and jumps through the time portal Bly opens before he can use it. In the "past" (that is, as seen in the episode "A.K.A. Kansas"), Brisco meets himself and takes the orb back to this present. (The dialog between the two Briscos is slightly different in the two episodes.) He returns to the present just in time to see Bly shoot Bowler. Enraged, Brisco leaps on Bly, and during the fight Bly is thrown out a third-story window, to his death.
Brisco tries to save Bowler with the orb, but is unsuccessful. Katrina prepares to take the orbs back to her time, but Brisco insists on trying to rewrite the history he just rewrote by killing Bly to save Bowler. When she activates the orb, he jumps through again. He returns to "the present" (with Bly now re-alive) and saves Bowler from being killed by Bly by knocking his gun away with an orb-rod.
Bly tries to recover the rod, but Brisco plunges it into Bly, which kills him. Karina returns to the future, and all is well.
Bowler decides not to retire to grow wine (in an area he thinks might be a good place to grow grapes, the Napa Valley.) President Cleveland himself congratulates Brisco and Bowler, and recruits them both to work as extraordinary agents for him when they're not doing regular bounty-hunting, with Socrates as their intermediary.
Did anyone else think that the music for this episode (with its quiet background piano flourishes) was rather X-Files-ish?
