LoglineAn accident while investigating a time portal sends Ensigns Beckett Mariner and Bradward Boimler through time from the 24th century, and Captain Pike and his crew must get them back where they belong before they can alter the timeline.
You kind of got the feeling the 23rd century officers were all left wondering why 24th century Starfleet is so unprofessional
I don't think it's the difference between 23rd vs 24th century officers, but more a difference between upper deck senior officers and lower decks ensigns.
