"Where could have he gone?" Taylor's baffled as she and Alpha haven't been able to find Paul, they've looked everywhere for him, but he hadn't shown, and she was still unable to contact him with their telepathic connection.

Wherever he is, he's still amid the mental blockers.

Trying to compel Alpha into telling her about the mental blockers proved difficult, it held whatever programming it remembered to heart, that no matter how Taylor tried, it would always default to, "Confidential."

Attempting her usual tricks did nothing to compel the odd robot to tell her what she needed to know, even most robotics would fall for her tricks with some persuasion, even the Daleks and Cybermen felled for her tricks, but Alpha was a special case, it seemingly knew Taylor was fishing for answers, and it wouldn't give them.

No luck finding Doctor Ivo, still, that much Taylor knows, Alpha had no problems mentioning that Doctor Ivo's somewhere in the complex, still.

Surprisingly, Alpha mentioned that there's a possibility that Doctor Ivo's in an "error" that it cannot travel through.

Selective programming, Taylor saw this before, there's probably an area that Taylor can see and move around in, but Alpha would not see a room, it would only see a wall of errors.

Find the "error" find Doctor Ivo.

Well, that should be easy, but Alpha mentioned multiple "error" that it cannot see or interact, that only Taylor can.

Only so many times she can go round and 'round before she finds the right "error."

More with a stilted robot that had a limited range.

Her emerald eyes looking up to Alpha, Taylor attempts to narrow the "error" down to something reasonable, hoping by doing so, she can effectively find the correct "error" and find Doctor Ivo.

"What about where you came out of…?" Taylor questioned Alpha about the area it appeared from when it came out of the false wall on a conveyer belt.

Alpha responded with a quirk, "Error. Not hospitable."

As in, where it came from couldn't be where Doctor Ivo was, as it'd be dangerous for him.

Ah, a hidden factory, an automated one, that's why.

"Could the Doctor be in the "error," Alpha?" Taylor asks it.

Perhaps Paul accidentally gotten into the factory, that's why Alpha's having problems finding him.

Growing silent as it moved forward with Taylor following it, Alpha replied, "Not hospitable."

Thinking, Taylor goes, "What is hospitable?"

Quietly, the robot continued to maneuver through the corridor, before finally saying, "Location locked."

Location locked, it's something, right?
Going through the corridors once more, Alpha ended up stopping in its spot, turning its large body towards the wall, Taylor asked it what it was, and Alpha said that it's an "error" but it was hospitable.

Thinking it over, Taylor then asked, "How… would I make the "error" go away?"

Silence, before Alpha finally spoke to her again, telling her in its stilted robotic voice that if Taylor goes through the "error" and finds a way to "fix" it, then it'd mean that Alpha won't perceive it as an "error" thus it can follow her through.

It didn't tell her how to "fix" the "error" other than it'd be confidential, but Taylor's willing to try anything to find someone in the complex.

Nodding, Taylor gestured, "I'll go check, wait for me, will you?"

She heard back, "Affirmative."

Feeling the wall in front of Alpha, Taylor could feel a light breeze coming from the hidden crevices.

With the metal flat piece, she kept with her, she stuck it into the crevice she found that fit the flat piece, slowly running it up, and down, until she heard the pressurized hiss, as the hidden door opened.

Sliding open, the false door revealed another corridor going up.

"Grace Taylor," Taylor heard her name as she turned her head to look towards Alpha.

Looking at it, Taylor asks, "Yes?"

She heard Alpha, "Corrupted dialogue."

It couldn't tell her what it wanted; something was still wrong with its programming.

"I don't suppose there's any way I can help you with your problems, is there?" Taylor offered Alpha a chance for her to help the robot and it stiltedly responded that somewhere in the hospitable "error" is what Taylor needed to help Alpha.

Sounded easy enough, find whatever's blocking Alpha from seeing the hidden doorway, have it found what it needed for Taylor to help it, go from there.

"I'll be back before you know it, Alpha!" Taylor tells it as she hurried through the opened doorway through the corridor into a hidden part of the complex.

Stepping through the threshold, Taylor made her way through the hidden corridor, nothing different than the corridors she previously walked through, other than this one was being hidden.

Strange that Doctor Ivo would find a reason to make these hidden corridors, even if he's worried about someone stealing his work, there's better ways of preventing them than making these long-winded corridors that are indistinguishable from each other that without a good knowledge of the layout someone will almost never find their way.

If the TARDIS couldn't pick up the hidden corridors and the factory, Taylor doubted someone else would've had the luck.

The dossier said nothing about Doctor Ivo having assistants or colleagues, he always worked alone, no one would've leaked the layout, that much apparent.

Coming out of the corridor, Taylor found she's in some sort of room with pistons covering the walls, pushing liquid throughout the complex.

Seeing the warning symbols gave Taylor a clue what those liquids were, and she cautiously moved away from them towards the end where there's a door with a red valve in the centre.

Unlike the previous valve door that wouldn't open without Alpha's help, Taylor was able to open it herself, the valve turned effortlessly and the door swung open, revealing a large chamber with larger pistons, in the center Taylor sees there's a control panel, one with a shiny red button.

Of course, in all media worlds over, everyone joked what horrible ramifications there be if someone were to push a red button, they had no idea what it was for, but for Taylor, it seemed like a solution more than an Aesop.

She stepped close to the controls, looking them over, and nothing indicated that the other switches and buttons did anything other than altering the pistons pushing liquids throughout the complex.

Like Paul taught her, sometimes a mistake is needed.

If only there wasn't a chance of causing a radioactive breakdown if Taylor made the wrong mistake.

Nothing else looked important or anything indicating that there was something Taylor overlooked, that she had no other choice but to hit the shiny red button.

Truthfully, she expected a black comedy or a slow burning horror, instead she felt a jolt while jumping back as she sees a hidden compartment opening outward, producing another, abet smaller, red valve.

Her hands around the valve, Taylor began turning it, she felt the click as something came lose, allowing her to pull up the valve.

Upon locking it into the place in the upright position, Taylor sees another hidden compartment open on the console.

This time, it was a key.

Not the most convoluted thing that Taylor dealt with, before, but it made her question why Doctor Ivo would go through the effort for this elaborate setup.

Reaching out, Taylor turns the key, upon doing so, she hears the wall beside her hiss as something appeared from behind the wall.

Pulling out the key, Taylor turned towards the wall, seeing that yet another hidden compartment opened, this time, it looked like an unusual input.

Checking it, Taylor found that nothing she had on her would work with the input, the hole wasn't for the key, it was a standard key compared to the intricate circle with circular spirals.

Having done everything here, Taylor went and found Alpha waiting for her as she asked, now telling her that it can see the room.

"Identified. Power source #343," Alpha monotonously tells Taylor.

There are dozens of power sources throughout the complex, Doctor Ivo made sure of it when he constructed the complex, the reasonings were pragmatic, had there been one grand power source, should anything happen, well, he'd be a dead man.

Have the power source splintered off in a sequestered matter, with the ability to turn them off at any point, quarantining them as needed, kept the fears of a full-blown breakdown from occurring.

"What about the input thingy, I don't quite understand what it's for?" Taylor asks Alpha about the input that appeared after she turned the key, Alpha slowly moved passed her as it trudged along the corridor, back where Taylor came out of where it stood in front of the odd input.

Something protruded through Alpha's "face" that gripped the input, turning it.

Upon doing so, the wall slid downward, revealing, once more, another corridor.

"Alpha, what room does this go to…?" Taylor inquires where this corridor goes to and Alpha replied in its usual stilted voice, "Creator."
