Chris Silber, the co-executive producer of the police procedural drama has teased that Eva Azarova (Cassidy Freeman) will play a major role in the crossover special episode. "When we last saw her she was on the way back to Washington. She's very much involved in the plot having to do with the playbook and these series of scenarios of how to attack the United States. She plays a big part," he told TV Guide.

Explaining the friction between the two teams Silber said: "Torres is a great example. He's brand new and Tammy is pretty new to the New Orleans team. They're both strong-minded, action oriented characters. There's tension between them for sure but they also find common ground."
