Twelve, though she wasn't one who tended to do so, smiled ever so slightly at the Ensigns observation.
While in some ways she elected to respect superstitions other people believed in as it was conducive to efficient function when one interacted with patients, she also lacked evidence to prove superstitions were true.
They were just things people elected to not do for some reason she'd not yet managed to wrap her head around. At least, she believed as much, so she smirked. Part from that, part from the fact that a ensign happened to have just done that.
However intentionally or unintentionally.
The smile or well, smirk passed swiftly, replaced by calm concentration though. While nobody at present needed medical attention, it paid to be prepared. So, she checked her med kit again, assurred herself all was prepared.
