Upon reuniting with Malcom, he says that the pair of Cybermen are still somewhere on Putnam, but since he didn't know what he was going against, he never chanced going after them, until now.

"They're still there?" Taylor's shocked hearing this, as Malcom affirmed that the pair of Cybermen have stayed on Putnam long after the attack on the school, and Paul says that there's a chance the Cybermen were scouting.

With Cybermen, there's always something logical to their illogical tendencies, and staying on a planet after completing their mission with their signatures broadcasting's one of them.

Re-entering the TARDIS, Paul brought them back to Putnam, upon exiting, they're shocked how different everything became after the attacks.

Even though the Cybermen focused on the school, nowhere around it, everything became no different than the planet they just left from.

Seeing the seediness of gangs roaming, the sight of the once pristine buildings turned into corpses filled with leeches and lurch, and it's leaching outward on the once beautiful planet where every student felt safe walking amongst themselves, even at night, Malcom morosely tells them that the planet used to be different, much cleaner, much safer.

The Cybermen attacking the school changed all that, once the surrounding area learnt what happened, understandably, residents fled for their lives, out of fear the Cybermen may come for them, next.

People of questionable backgrounds took instant notice of this and swooped in, taking over the ashes, rebuilding the one former prospecting planet into their own image.

Vultures, Malcom calls them.

Picked the carcass of his former home clean, made a foul nest out of the bones.

Like insects, they fostered their control in every corner, that authorities can't do anything but simply warn curious travelers away from the planet, cordon it off.

Almost wished the Cybermen went for them for further destroying his only home, but Paul chided Malcom in an instant the stray thought popped up in his mind.

No good could ever happen wanting Cybermen around, Paul reminded him.

Even though it hurts seeing his planet become this way, Malcom can't ever wish this happening.

"They're somewhere near here," Malcom looked at his handheld tracker, Paul confirming this with the Sonic Screwdriver.

The trio worked with the tracker and the Sonic Screwdriver guiding them through the bazar of strange and macabre.

"What happened to them, Doctor?" Malcom asked Paul what became of the two women who attempted to help him with the identification of the Aerographene Cube.

He vaguely remembered one of them and when Malcom gave the description of the other woman, Paul's eyes glistened as he instantly knew who Malcom spoke of his dear mum.

Keeping it vague, Paul informed him what happened to the women after that day, the answers satisfactory for Malcom as he didn't pry for more information.

Working in tandem, the trio followed the signatures.

With the signatures faintly broadcasting, it led Paul into believing that it's why the other Cybermen haven't become aware, the same for Daleks.

Still, better safe than sorry.

Following Paul closely, Taylor's curious emerald eyes glimpses at the things sold in the bazar.

Openly, there's traders selling Red Spice, attempting to lure potential customers by hyping their product, at least two rivaled one another over the potency of their drugs.

Salacious types ogling any female aliens, on almost every corner, one looked straight at Taylor with malicious intent in those iridescent tiger eyes, before Paul shot a nasty glare their way, and the alien swiftly broke eye contact from Taylor, pretending it hadn't done it, fear latent in the iridescent tiger eyes.

Nauseating smells of different narcotics being smoked intermixing, that even the stagnant breeze couldn't push out of the bazar.

Had to hold their noses to barely breathe until they're pulled towards an alleyway where it's littered with rubbish and there Malcom catches sight of an inquisitive alien looking them over.

Three eyes, shorter than Taylor, blue scales, long droopy ears with piercings, wore brown robes, and moved slow as it tried getting a better look at them while it emerged from behind the streams of beads hanging over an entrance.

It went in chirps and trills, "Rare sight, seeing your kind!"

Narrowing his blue eyes, Malcom responded in Common, "We want no trouble, we'll be on our way, now."

The alien raised its three clawed hands as it insisted, "But I know what you are searching for, yes, yes!"

It invites the trio into its lounge, though they remained on-guard as they passed through the hanging beads into a dim-lit lounge filled with bottles of oddly coloured liquor, tables setup with hookahs in the center.

"Who are you?" Paul questioned the alien as it guided them through its lounge.

Going around the corner of the bar and hopping up the stool to look at them at-height, the alien calls itself Krill.

"You must be looking for the dogs!" The alien assumed what the trio were looking for, causing confusion among them as they asked Krill what he meant, and he explained further.

Gesturing his three-claws, Krill tells them that there's been a recurring issue with "dogs" causing problems.

"What does this have to do with us?" Taylor asks Krill what he intended with corralling them into his lounge.

Pouring himself a drink from one of the unique bottles, Krill coyly answers in his chirps and trills, "I used to rummage through the ruins of that school. Found a picture of him, that's why."

Pointing at Malcom directly, Krill informed the trio that he'd found the picture among the ruins, and since there's hardly humans among Putnam anymore, it didn't take long for him to guess that if Malcom wasn't dead, he'd turn up eventually, for revenge.

"You know of them?" Paul asked Krill if he knew about the Cybermen and the alien confirmed this, telling him that they mined his planet empty of minerals and metals for their chassis.

In the ensuring rebellion, Krill's people were no match against the metallic fiends, and only a handful escaped total annihilation.

"How did you survive?" Taylor asked Krill as he drank from his glass.

Resting his half-drunk glass on the bar, Krill replied in a chirp, "I hid from the Cybermen in one of the boxes in the warehouse I worked until they stopped searching for survivors, then I made my escape here. Not many of us exist, now."

Raising his finger, Malcom asked Krill what he meant by "dogs" and Krill laughs as he trilled, "Those dogs are looking for Cybermen, too. I escaped death once, I don't intend doing it, again. Ironic, me coming here!"

Those troubles he mentioned, the dogs have been known to act out aggressively towards the new residents on Putnam if they get too close to their master.

"Why are they looking for Cybermen?" Paul inquired the reasoning why these "dogs" as Krill referred to them sought the Cybermen.

Shrugging his small shoulders, Krill informed Paul that he didn't know, only that they've acted aggressively towards anyone who got too close to their master.

"All I know is, nothing good comes when those dogs are in an ugly mood," Krill summed that it's become wise in this area to avoid them.

He tells of an incident where the dogs dealt with an aggressive peddler that wouldn't leave their master alone.

If the trio looked close enough, they'd find some remnants of the peddler.

"What dogs are they?" Taylor inquired what they were, and the alien chortled, telling her, "Not any dogs I know of, one had blue eyes, one has red eyes, when they glow, trouble brews!"

Curios and a little suspicious, Malcom asks why Krill's telling them this, and the alien gave a practical reason after taking a drink from his glass.

"It's bad for customers if they're too afraid to come through here, they don't even want to risk bumping into them. I figure, you are all the same, maybe you can call them off, ey?" Krill pointed at them as he gave his reasoning.

Since his problem's an alien, like the trio, they can communicate with it and have them shove off, so their dogs stop scaring prominent customers.

"If they keep on, someone's going to get irate and I'm not interested in moving so soon," Krill pointedly told them as he looked at them with his three eyes.
