Threaten him

From Create Your Own Story

"You smug little asshole," you snarl at the officer, grabbing him by the collar with both hands, "do you know who I am? Do you know who sent me here, in this stinking cesspit you call a city? You're going to tell me where's the captain, right now, because what is going on is much too important for insignificant underlings like you to understand, let alone handle!"

There are many much less polite things you would like to tell him, but you do not have the opportunity : you are hit behind the head by a blunt weapon and fall unconscious.
