In the teaser of this episode Taneka says "You may think you have won. But you have yet to face the spirit of the kamikaze." This line is not included in the actual episode.
Cut scenes include RC3 and Michael leaving the O'Brien complex (and Michael promising Coy he'll take him for a ride in his "super car"), and Tanika's rant "They think they have won - but they have yet to face the spirit of the kamikaze!" (which appears in the episode's teaser).
In the script, Nick O'Brien is described as "a bulk of a man, his face eroded by time but with Irish spirit still lighting the eyes."
Devon knows Nick O'Brien from the Korean War - they both served aboard the Allied Command in the early 1950s.
