The fate of the family being held by Wiegler and Isaacs in the film Hanna is never shown. But then you realize that they've senselessly killed everyone else they've interrogated: the Moroccan guy, Hanna's grandmother, the clown near the end. Horror ensues.
Well, the original script has it that they survived, so that's something of a relief.
How did Hanna know that the fake Marissa was a fake, and that she would find information about herself in the research lab? Her hearing is super-sensitive, which allowed her to hear the chatter in the fake Marissa's ear bud: Marissa giving instructions to her double and Carl discussing the DNA test results.
In the first-season episode "Forest," Arvo remarks that Hanna eats "like an animal." In "City" and "Utrax" Hanna displays uncanny "dog whisperer" abilities. In the second season, we learn that Hanna was genetically altered with wolf DNA before she was born.
The Utrax girls aren't consecutively numbered. The next highest number after Trainee 242 is Trainee 249. One suspects that Trainees 243 through 248 proved unsatisfactory and met the same fate as the babies that were Hanna's contemporaries in the first iteration of Utrax: euthanized and burned in the incinerator.
