After Crockett asks Gina, Trudy and Stan for blood, Gina is seen playing with a snow globe on her desk. This may have been left by Zito, as she is sitting at his former desk and Crockett and Tubbs found out he collected the globes after his death in season three.
The episode features Crockett experiencing several flashbacks, including to scenes never actually witnessed first time around. While this technique has been used several times previously in the series with regards to Tubbs (particularly concerning the shooting of his brother Rafael in New York), this is the first time Crockett has been seen having flashbacks. Flashbacks would later become a significant and repeated plot point during Crockett's time as Sonny Burnett at the beginning of season five.
The argument between Castillo and Crockett ("What does he want me to SAY?!") was shorter in early drafts of the script before it was extended to the version used in the broadcast episode.
This is the first appearance of Caroline and Billy Crockett since Calderone's Return: Part 1 - The Hit List (1984). It also marks the first appearance of Parris Buckner as Caroline's future husband Bob Ballard.
Much like he did at the end of Death and the Lady (1987), Crockett again viciously attacks an unarmed suspect without provocation (Holiday). Such outbursts would have been unheard of in earlier seasons, perhaps a sign that Crockett is becoming increasingly worn down by the stress and perceived futility of his job. In fact, Crockett goes further still when he finally corners Monroe atop the large gas storage tank at the end of the episode -in hesitating to save him after he falls over the edge, he essentially allows Monroe fall to his death.
