On page 1 of the story, Wash admonishes Zoe, as regards her seeming to side with Mal, "Honey, remember the conversation we had about taking sides?" This may be a reference to Wash's feelings that she was too close to her old army buddy, Mal, in "War Stories".

On page 1, it's possible Mal, Zoe, and Wash are meant to be standing in front of the door to Kaylee's quarters; notice that panels 5 and 7 have some weird dots sprinkled along the corridor wall, which may be representative of the Christmas lights Kaylee is seen to have on the door to her quarters as seen in episodes of the TV series.

It's unusual that on pages 2-3, Jayne is wearing a plain t-shirt instead of one of his customary printed tees.

It's somewhat subtle, but notice that the heads of Shepherd Book and Kaylee are seen through the windows of the infirmary as Simon examines Jayne's "nethers".

It looks as if the Mule may be present in the cargo bay on panel 1 of page 7. Even though the 4-wheeled bike was seemingly sacrificed in "War Stories", it will also be seen again in the cargo bay in "Trash". It appears that the crew was able to salvage the vehicle, for parts and whatnot, from Niska's space station before they left in "War Stories".

River walks out into the snow barefoot. She will do this again in "Return to Earth-That-Was" Part 4.

River's comment to Book on page 8, "It's easy for you, too," is a reference to his secret past as Alliance agent, as later revealed in The Shepherd's Tale.

Unanswered Questions

Who were the people that River killed on the planet? It seems clear they were aiming to capture her, but were they waiting specifically for her, knowing she was wanted by the Alliance? Or were they just looking for a straggler to kidnap for slavery or ransom? If they were waiting for her specifically, how did they know she was on Serenity?
