After the emotional ending of part 3 in the series, this part features a combination of way more alone time with inner monologues and strategizing, as well as more action, once Murderbot discovers his old original crew might be in danger and Mensa is likely kidnapped for ransom.

After all the action and fighting, they are for the first time truly faced with the decision to decide where to go and what to do without being seen as a SecBot and with free will.
