5. Depiction of trauma is true to the emotion

In this episode, each cadet is experiencing some level of trauma following the USS Miyazaki incident a couple of episodes earlier in "Come, Let's Away." The cadets are young and unequipped to handle the feelings they are experiencing, and, by this point in the series, the fallout across the academy is massive.
SAM is especially unable to process her grief. Essentially an infant, SAM begins to glitch from the damage she took at the hands of the Furies, and her programming is literally unable to process her feelings. While this depiction is very science fiction-oriented, it is a great, subtle commentary on what we as humans need to support our own emotional intelligence.
If you were 18 or 19 years old, how do you think you would feel after an attack that resulted in the loss of several of your comrades? This is the first time our cadets have truly had to face mortality, and they have done so in the ultimate way. As such, their grief is strong.
