Give thanks to the healers.

Give Tom a break. He got forced into being the nurse because he took biochemistry classes before getting kicked out of the academy.

Plus, he's juggling nursing duties with his full time job as the pilot. And his side gig as a commando team leader. While moonlighting as a spy. And despite all that he's still finds the time to develop an encyclopedic knowledge of twentieth century earth. And let's not forget that he also designed engines with a top speed of infinity. He's the most competent man in Star Fleet. Not bad for a dropout and ex-con.

Pretty sure if you Tuvixed Paris and O'Brian, combining Paris's competence with O'Brian's work ethic, you'd get some sort of god.

But can any of those other nurses tune a carburetor?

I don't know that Kes was all that good either. She just followed around The Doctor and did whatever he said.

Objection! That's a picture of Doctor Ogawa, chief medical officer of the Enterprise in an alternate quantum reality.

I'm sorry are we including Dr. Toby "Bodycount" Russell in the good column?
