The moment the students have finished the barricades, Javert shows up. Disguised as a French commoner, he tries to infiltrate the club of “the little schoolboys” as he refers to them. He volunteers to sneak behind enemy lines to figure out the strategy of the National Guard. Enjolras, even though he’s never seen the man at any of the ABC café meetings, responds with, “Sure, buddy! Way to go!” and sends Javert on his way. He returns of course with bogus info, but everyone is duly impressed. Luckily, Gavroche, the top banana of the street urchins, recognizes him. “This is Javert, you morons,” he says. “The one who calls us whores and vipers. Remember?” They do and mutter, “Whoopsee!” and point their guns, spades and whatever other farm equipment they have lying around at the cop in disguise.
Another visitor enters:
….and shows off his impeccable shooting skills, killing a National Guard sharpshooter. Javert looks worried.
