"Then stop doing machine learning. Static algorithms are probably just as good half the time."

"True. Also, if the machines go all scary robot skeleton on us, paint your hideout with lots of lines and complex patterns. It'll be harder to find you."

He's just repeating it in case Dennis didn't see the billboards he's put up.

"Wouldn't a place painted with lines and patterns be more obvious that something's hiding there, even if it's hard to see?"

"Shoot. Better repaint that one later."

"Just don't give any of them GLaDOS voices..."

"Or cover them with fur. That makes them angry."

He then does a pitch perfect imitation of a certain kill-screech from a certain game.

People are mostly confused, less unnerved.

Dennis throws a popcorn kernel at him.

He giggles.

Meanwhile, Tabby's horde is providing security. Mostly involves telling people the time. And sniffing people for contraband as they come off the buses. 

The average quality of bus-goers is pretty good. They all seem to behave, and while some are reluctant to go without their weapons almost none of them make a fuss.

The average quality of those who arrive by walking or driving in from the surrounding area is a lot more varied. At least one group is going from stall to stall, looking for things to steal.

And Tabby is following them, smiling beautifically. 

If it's any comfort to the children who relinquished their weapons, they were all given a number for reclaiming them when they leave. 

After buying a few slices of apple pie from one food stall, one of them walks off with apple pie and a bag of flour in his backpack...

"Could I see your backpack, sir?"

"Uh... How about no? It's my backpack."

"Really? You're trying to fool the superpowered vampire? I hear your heart beat faster."

"I'm not gonna let you look at my stuff, you're not a cop."

"No, cops have rules."

"You're just trying to bully us. They call you madchild you know."

"Yes, I can hear them. And if you just give me the flour, I won't even kick you out."

They have a quiet, not-nearly-hushed-enough debate.

Just give it back, not worth it, says everyone except the guy who actually did the stealing.

That guy makes a run for it.

She is in front of him. Smiling.

He tries to shove Tabby out of the way.

The bag of flour goes flying in the ensuing collision.

"You just had to be dumb, didn't you?"

"Lemme go can't do this!"

"I'm willing to be lenient. A day or two of community service at the hub? I'll even escort you home afterwards."
