On page 4, Zoe reveals that she is a former member of the Dust Devils terrorist organization.

On page 8, Jayne asks, "Now, when are the purple-bellies gettin' here?" "Purple-bellies" is a slang term for Alliance soldiers, for the purplish armor they wear.

On page 21, Mal confronts Inara about his having seen Simon leaving her shuttle while she was attending to business on Pelorum, but she doesn't give him an answer as to what Simon was doing there. Possibly this is related to the subtle Inara subplot mentioned in the DVD commentaries of the episodes "Government Goods" and "Out of Gas" and her trip to Ariel in the episode "Ariel" for a medical checkup. (It was also revealed in the 10th anniversary reunion special Firefly: Browncoats Unite, which aired on the Science Channel on Sunday, November 11, 2012, that Inara does has a terminal disease which would have been introduced into the storyline if the series had continued. It may be that here, Simon, as a doctor, has been let in on her medical issue.)

In the very last panel of the story, we get a better look than usual at the strange extra contraption on the outer hull of the bridge area of Serenity. The Official Serenity Blueprints reveal it is a set of solar panels.
