- End of report. Ko concluded, leaning back in the pilot's chair.

- Report 21 saved and sent successfully. - The on-board computer informed.

The cockpit was silent, only the sound of the electric current accompanied by his heartbeat.

- Computer?

- What can I help with, Captain Lovei?

- What is your opinion on the current mental state of the passenger Teo Jak?

- Without concrete tests it is impossible to say for sure, however records show that he has not been sleeping the minimum recommended 12 hours, that he has been skipping meals and has not been taking care of his hygiene. These may be symptoms of depression, but concrete tests by a specialist would be needed to give a diagnosis. The robotic voice responded after a few seconds.

- He's not well...

- Passenger Teo Jak has returned. - the voice announced.

Ko sighed and stood up, following the sound of footsteps to the room next to his. The anthropologist had covered his room with a collage of photos, drawings and maps. Everything from that planet, everything from the humans I would never know.

Teo put his suitcase next to the secretary and sat down. He didn't greet the other leaning against the door frame, nor did he look at him. Teo just grabbed the disks inside the suitcase, and, one by one, inserted them into the computer's disk drive built into the desk.

- Teo, do you want to go eat something? - He didn't get an answer - Now that I think about it... Didn't you want to try genuine human food? I bet Gabi can teach us how to make "pizza" for real. The human way.

Teo paused momentarily when he heard the proposal, looking around for a second.

The anthropologist got up and calmly cleaned the walls, crumpling each decoration and stuffing them into the garbage chute.

Ko did not intervene, but managed to save a small drawing, discreetly stuffing it into his pocket.

- Teo. - he called the paralyzed man in front of the chute's door - Teo, talk to me.

- What's there to talk about?

- Teo, look at me.

The other turned slowly, as expected. He had that all-too-familiar opacity in his eyes.

- You are on autopilot. The moment this expedition ends, you'll start to fall apart. - Ko explained - I don't want that to happen. Please talk to me.

Teo sat down and turned back to the computer.

- Talking won't change anything. Let me work in peace.

Ko sighed.

- You know where to find me if you need me. - The pilot said, leaving the room.

The doors closed and Teo continued to transfer his notes to a compressed file.

When he finished his task, he got up and left the ship, his suitcase now full of disks ready to store more data.

Gabi continued to teach him everything there was to know about humanity. If its technologies were compatible, it could do a simple data transfer, but visitors must have spent all their good luck to find it, so Teo ended up sitting in front of the console, something akin to a tablet in his hands.

- And so the slaves claimed their– Teo, are you okay? - She asked, interrupting the lesson.

- Huh? Yes, I'm fine… - he blinked slowly, - You may continue.

- No, it is not. - the woman on the screen said - Your mental state seems to be severely deteriorated. I cannot, in good conscience, ignore—

- Gabriela, continue the lesson. He ordered in an authoritative tone.

-No.

-No? What do you mean "no"?! - he asked, getting up from his chair - You're an algorithm, you take orders and obey!

- Teo, although it is true that I have to obey orders from users, I reserve the right not to comply with orders that go against their well-being or the law. Continuing the lesson would delay the treatment of your mental state.

The room fell silent, Teo falling into his chair with one hand on his head.

- Teo, what's the problem? - She asked in a comforting tone. - What is making you so sad?

- What do you think it is? The humans, who I spent 93 years studying, are dead. I wasted my life and... they're all dead! Not to mention that I did a terrible job. I won awards for my studies, but I was saying stupidity after stupidity! I'm an idiot...

- Teo, while it is true that 111 is an advanced age, one can never be sure how much time we have left! The record for oldest person belongs to–

- Gabi, I'm not that old...

- Oh, how old are you then?

- I recently turned 100. - He clarified - We lived about 400 years. Right now I am the equivalent of a young adult human.

- Interesting! What else can you tell me about your species?

- Want to know more about my species?

- You're not the only ones who like to learn new things about other species! - she said, crossing her arms - I've been teaching you about humans, non stop, for the last few days. You could return the favor.

- Okay, I think it would also do me some good to give my wrist a rest.
