"how long can octopeople stay alive without food?" he asked while pondering.
[they can enter a low calory usage state and hold more than a week]
"hmm, I better wait some days then, if she's hungry and I give her food she would be more grateful"
[it's an intelligent being, not a "wild dog" from your world, it could also resent you from keeping her there]
"ah...hmm, well I'm an engineer, not a psychologist, what is your advice?" inside thinking 'i wasn't such a bad idea right?'
[graphics, graphics are universal there's a screen on the garage, I can emit your face and voice there, just started printing the camera device]
"that's great, that should work"
he sets the synthesized device on the kitchen table and turns it on, his face appears on the garage wall and Rose turns on the lights there, the tribal scout is shaking in fear, it's too much.
"How did she react?"
[shaking in fear and peeing herself..., now she's releasing paralyzing poison from her skin preparing for an attack]
"well, let's wait until she calms down then"
seeing the face on the wall not move and nothing bad happening to her she calmed down and approached.
[she seems calm now]
"good" (he can't see or hear her, so he depends on Rose for that)
You might be reading a pirated copy. Look for the official release to support the author.
he writes his name on a sheet of paper and shows it to the camera while pointing at himself.
"my name is Erik and yours?"
[that won't work, she might not even know what a "name" is, to begin with, and she doesn't know what you are saying]
he facepalms "am I stupid Rose?"
[haven't met any other humans so I can't tell sorry]
"well, I have another idea"
he takes out the laptop and turns it on, luckily the wall charger in the space was designed to adapt to hundreds of civilizations so it changed voltage and shape automatically to 240V to plug it all the technology, the algae chlorella generator would take some days though, he puts the camera showing the screen of the laptop and shows a picture of the spaceship, then points at himself and then the spaceship turning the camera.
[she seems to understand that]
"Finally, progress, let's use my average drawing skills then"
he clumsily draws the spaceship hitting the ocean floor and himself retrieving things, and then an octowoman chasing him, he signals it and then to the camera.
[she's now in front of the screen, she doesn't look scared anymore]
"let's continue then, I have a mission for her that could be a win-win for both"
he then draws himself with a spear and giving it to her, then she going and hunting animals and then both eating those together, then he cooks a dish of crab in the kitchen looking tasty and records himself eating
[she's salivating, it seems to be working]
then he draws her coming through the hatch and eating from a plate and pointing at a second dish he made with a bit of pepper and salt on hers, he can't afford more until he grows more.
[careful, she looks just a bit smaller than you but her appendages are way stronger, her hands could twist your arms easily]
"damn, I'm the one scared now"
[well, you are weak after all]
"I know okay? jeez, this is a freaking super evolution monster world after all... sigh... I feel tired now"
[the camera is still on]
"yeah, the girl, right, let's just hope she doesn't kill me"
[well, I can control the weapon on your shoulder and help you if things look bad]
"oh... I feel better then"
he puts the suit on, something that surprises the octowoman seeing, and he grabs the camera recording the dish and a fork, not a knife for obvious reasons, and places it outside the pool on the far end of the garage, then he retreats to the door and closes it, looking through the small glass panel on the door.
"...open the hatch Rose, just enough for her to fit through"
[opening..., she's reacting and approaching]
