“Face it, Q,” Picard told him. “You’ve been hanging around humans too much. Your system has not been able to build up proper immunities to us, and we’re becoming contagious. You’re coming down with a terminal case of humanity.”

“Picard,” said Q, with a bit of the old arrogance. “Get some hair. Your brain has caught cold.”

And with a burst of light and sound, he vanished.

“Good riddance,” rumbled Worf.

“Oh, I don’t know,” said Picard slowly. “I hate to admit it… but I’m starting to get used to him.”

“Captain, you’re joking!” Riker said in horror.

Picard turned towards him. “Oh, of course I am, Number One.” But he wasn’t entirely sure that he was.
