Ivanova: Always finding the good in every situation, eh Captain?
Sheridan: Absolutely. If I didn't, I might end up like you.
Ivanova: Hey, what's that supposed to mean? Did anybody hear that? Did you hear that?
Corwin: No, Commander.
Ivanova: Good. I swear, if we live through this, somebody's going to find their shower preferences reprogrammed to ice water... (edit) Ivanova: If I live through this job, without completely losing my mind, it will be a miracle of biblical proportions!
Corwin: Well there goes my faith in the Almighty. (edit) Ta'Lon: To leave now that I have decided to stay with the others, would be rude (draws his sword) ... and uncomfortable.
G'Kar: That is a G'Thok. Once unsheathed it cannot rest until it draws blood. Again you would raise weapons against your own kind? Have I taught you nothing?!
Ta'Lon: I carry my sword in my hand. You carry yours in your heart and in your mind. As I see it, that gives you a two-to-one advantage in arms. Be fair, citizen G'kar. (edit) G'Kar: If I stay here, your families are in jeopardy. Is anything more important than their safety?
Narn: Yes, their freedom. (edit) Ivanova: Captain, are you all right?
Sheridan: Nuts.
Ivanova: What's wrong? I mean, we've survived.
Sheridan: Right, which means that I have to go to that stupid transport association meeting. Oh, well.
(Sheridan walks away)
Ivanova: If I live through this job, without completely losing my mind, it'll be a miracle of biblical proportions.
Corwin: Well, there goes my faith in the almighty. (edit)

Continuity: Sheridan order a Securebot to examine the probe. When the bot is shown, however, it is labeled "Maintbot 12." (edit) Continuity: Near the end of the episode Sheridan asks how many security bots are near the probe. He is told that there is one. When the security bot is shown, however, there are clearly two identical-looking bots present. (edit)

Sheridan: ... a berserker...
The probe is refered to as a beserker. This is reference to the "Berserker" novels by science fiction writer Fred Saberhagen. These novels feature powerful automated war machines that seek out and destroy biological sentients. (edit)
