Tuvok
With the Sorting Hat covering his ears, the only thing that identified Tuvok as a Vulcan was the calm expression on his face when most people looked nervous or embarrassed.
"RAV—" The hat cut itself off. "Most Vulcans are that house, but you chose to be a security chief…our choices more often define us than our nature, hm…but you use your logic for that job, so I was right to say…RAVENCLAW!"
Vorik
Ensign Vorik regarded the hat as calmly as Tuvok did, and the hat noticed.
"Ah, another Vulcan, this one in a more traditionally Vulcan job, Vulcans are…RAVENCLAW!
Wildman, Naomi
In contrast to the members of the crew who were older than the normal age of Sorting, the member younger than said age strolled up the hat confidently and eagerly put it on.
"Very self-confident, intelligent, a drive to succeed in your endeavors—oh! A desire for power and status…"
"I want to be the Captain's assistant," Naomi said solemnly.
"Yes, you do… you also show great compassion, as you befriended Seven of Nine—though you've been learning from her, you too desire perfection. Coupled with your ambition, very Slytherin."
"No, not Slytherin!" Naomi cried. "That's the bad house! If I'm like Seven, put me in Ravenclaw!"
"You are her protégé…RAVENCLAW!"
A/N I was debating between Seska and Naomi, but I chose Naomi because Seska would be too quick, an automatic Slytherin. Up soon...The Doctor Sorts Himself!
