So, how did Cadet Pickford make it past the psychological screening to get admitted into the Academy? Between eating her comm badge, walking in circles repeating red alert in the premiere and now having a complete meltdown upon seeing a corpse floating in space, she really doesn't seem up to serving in Starfleet.
And before anyone starts with "she's young, this is likely her first corpse" I point out Genesis and Darem are probably the same approximate age as her, and this could well have been their first time seeing someone killed, but they kept it together a lot better.
