Write either: A sci-fi character turns up at the table for your victim to easily repel the attack.

Or: A fantasy character knocks on a door until a killer is uncovered, who murders the character.

At the westerncoast bar where flew me and me mates, Henri and Percudor we got a table with an unknown commander who we thought was a red. We didn't care much, being lenient in this matter of communists. Goddamn reds. Couldn't find any when you wanted, but they showed up all over town when the cops eased up.

I knew in a second who would win the scuffle based on who started it. It was the reds. We easily repelled the attack, one with his mouth-onion gun, a breath attack, air form. The next attack was a quick zap through the eyes to check our sanity, a test we easily passed and overcame the attackers.

Our fiction abilities were harmed during the brainy scuffle. We couldn't tell the difference between a simulated stimulus and a real one.
