"You ain't dismissed yet!" McCoy yelled, storming after Spock.
"I am your superior." Spock turned to him. "You cannot 'dismiss' me."
"You're my patient. You stay 'til I discharge you."
"A patient may discharge themselves if they may receive better care elsewhere."
McCoy drew up sharply.
"Fine. You don't think I'm caring enough then you go see if M'Benga will care properly."
He stormed back to his office. Spock followed.
"I did not intend to imply you were lacking in care," he began before the door shut behind him.
Jim turned to Christine.
"Spock's ill?"
She looked up.
"He sneezed."
