Mariner Underestimates Boimler

After Agimus reveals Mariner had Boimler reassigned to a safer mission, he gets into a physical fight with her which completely catches her off-guard. When Boimler aims his phaser at her, she thinks he doesn't have to guts to shoot her but he does it and she gets stunned. She's later impressed when Boimler reveals it was all a trick to gain Agimus' trust and have him power a ship to send a distress signal without his knowledge.
