"It's unethical to harm a patient. I can inflict as much pain as I like."

That sounds like something Garak might say.

And Phlox did look quasi-Cardassian, didn't he?

As a nurse who works with a difficult patient population, this is my favorite quote.

It was funny, but I feel like what he’s saying isn’t clear without context or extra elaboration, which is why when I first heard I was like “How is inflicting pain not harming”

When what he really said was “It’s unethical to harm a patient at all. It doesn’t become more unethical to harm you more”

When he tells archer that his dog will blend into the environment when scared because of chameleon dna.

As long as he doesn't like to inflict enough pain to cause mental or emotional trauma.
