I'm sure that his constant lying will eventually bite him in the ass in the future whether the final day comes to discuss who they choose to be the best candidates or at a later point in time. In the end, I still think JAXA will still probably accept his position as an astronaut. This might be the case because of the foreshadowing where the psychologist asked, "Did you find anything new about yourself recently?" again and the candidates will have to answer the question.

Still, it gives great insight into the mindset of adult psychology and how most adults may lie and are unwilling to apologize for their mistakes or admit to their wrongdoings. This factor will definitely separate Mutta away from the other astronaut candidates (if they're shown to be malicious and stealthily deviant).
