Goof: As the naked female terminator walks up the bus aisle, her hair is initially clear of her neck, but she apparently brings her hair forward between shots for modesty's sake.
When John fires his gun at the beginning of the episode we see, that the bullet went into the wall, but in the end of the episode John is staring at a bullet hole in a mirror, although there was only one shot fired.
It is revealed that it was John who killed Sarkissian in the premiere episode "Samson & Delilah."
Sarah: (opening narration) My father slept with a gun under his pillow. There was no pill for his sickness, no medicine to ease his mind. He left blood, and sweat, and part of his soul in a foreign land. My father never talked to me about the war he fought. He never talked to anyone. Ever vigilant, ever silent. I never thought I'd follow in his footsteps.
Sarah: (voice-over) In 1678, doctors diagnosed the mental affliction soldiers suffered from as nostalgia. Homesickness. A longing to return to the past. The cruel reality of war is that there is no return home. No return to innocence. What is lost is lost forever. Like my father, war's wounds have bled me dry. No words of comfort. No words of forgiveness. No words at all.
Sarah: John is not suicidal.
Derek: No. But what is he? He's not a boy. He's not a man. He's not a soldier. He has changed.
Cameron: (reading a leaflet in Dr. Sherman's waiting room) Did you know that sixty percent of all teen suicides are committed with a gun?
Sarah: He thought it was cleared. It was an accident.
Cameron: Some first attempts may appear to be an accident.
Sarah: (discussing the next name on the list) Dr. Boyd Sherman, child psychologist, family therapist.
John: Well, what's his link to Skynet? Friend or foe?
Sarah: Don't know.
Cameron: Skynet doesn't have friends.
John: (annoyed) Well, it's got foes, and whatever the opposite of foes are, okay?
Derek: I doubled back on Sherman's house. I got nothing. How was he?
Sarah: Curious, smart, annoying.
Derek: So he's good at his job?
Sarah: Better than we were at ours.

After a five episode absence, Sarah's monologues return in this episode. This marks the first time she has provided the opening and closing voiceovers in the second season.
Leven Rambin and Garret Dillahunt do not appear in this episode.
Marooned in Realtime:
When Jesse is explaining that she's is in the past illicitly, she says she has a "friend who is a bobble-tech". Bobble is a term coined in Vernor Vinge's books The Peace War and Marooned in Realtime. Bobbles were artificially created stasis bubbles which held their contents frozen in time, until the bobble would decay naturally and release their contents back into normal spacetime. In Vinge's novels bobbles were used to send people and objects forward in time (sometimes involuntarily) and could not be used to travel backwards in time, so the analogy is not perfect, but as both bobbles and the effects of the temporal displacement equipment used in Terminator are spherical force fields, the two are reminiscent of one another.
Kill Bill: Vol. 1:
When Cameron is fighting the other terminator in the elevator of Dr. Sherman's building, they stop and try to "act natural" when the doors open and some people get on. Only one little boy notices how roughed-up they both look. This recalls the scene at the beginning of Kill Bill: Vol. 1 where "The Bride" is fighting with one of her former female co-workers when the woman's little daughter comes home. They both stop fighting and pretend nothing is wrong, even though they, and the room, are thoroughly trashed.
