She nervously waves her hands in circles. Then she takes a deep breath and takes out her phone, showing Kellen a photo of a bedroom before nodding.

He… knows what a bedroom is? He doesn’t know what she means though. He frowns and tilts his head to one side, trying to wordlessly communicate his confusion.

Then she moves to a simplified cartoon drawing of a person sleeping in a bed, before... trying to emote curiosity at Kellen; she feels incredibly awkward.

He’s going to guess that she’s asking if he has somewhere to sleep and shake his head accordingly. And hope that his interpretation is at least somewhat right.

Cynthia nods to herself before moving on. She quickly takes a picture of herself, and shows it to him before having the phone say her name. "Cynthia". Then she moves to simple cartoon illustrations of different things, having the phone say their names. She then takes a few steps, hoping he begins to follow her.

Kellen gestures at himself and says his name in reply to hers. He also quietly repeats all of the words, feeling out the sounds. 
When she begins walking, he immediately follows.

(Oh! She should have thought about what happened after that) After a long walk, Cynthia takes Kellen to a skyscraper. She waves her phone in front of the door for a moment, and it smoothly opens to reveal a row of elevators. Cynthia points upwards, after pressing a button to call one of them down. She finds an image of an apartment building similar to hers, shows it to Kellen and smiles at him.

Pictures and pictograms aren’t the best at clear communication -although they’re much better than nothing- so he’s once again guessing at what Cynthia means. He can’t quite figure out why she’s showing him that picture but she’s been trying to help him so far. So, Kellen just nods and smiles.

She exhales as she takes the elevator up, grabbing a cylindrical key and opening the door to her apartment. It's mostly an impressively spacious open-concept room, and Cynthia gives Kellen a quick look at the compact bedroom and roomy bathroom, with a sliding door in front of the alcove separating the toilet from the rest of the room. Afterwards, Cynthia tries to give Kellen an impromptu language class, starting by saying how to introduce yourself and... hoping she's explained everything well enough for Kellen to respond.

The room looks very nice to him too. Once they’re finished looking around and begin the ‘lesson’ he listens intently. He thinks that stuff like yes and no would be a better starting point but any learning is better than none and he can’t really complain anyway. 
Kellen is pretty sure he’s understood Cynthia’s explanation, at least enough that he tentatively reintroduces himself, following her example.

Cynthia is pleased! She tries to be a good source to learn from, before deciding that he'd probably want to learn some words on his own. She hands over the phone to Kellen, showing off a program with quite a few cartoon illustrations of words for him to tap on and learn. She finds a photo of a plate with some kind of red meal on it, and repeats its word to Kellen again.

He does like learning more on his own! He’s not sure what she means with that image though. Is the word for food? Or is it that specific meal? Well, assuming that she isn’t trying to tell him something, he’ll just repeat the word again. Hopefully learning more words will help with the ambiguity.

Cynthia touches her chin for a moment, before quickly tapping a few buttons on her phone before returning it to Kellen. After a short wait, the chime at her door sounds, and Cynthia walks out to get the food from the short, wheeled robot. She brings the steel box of food back in, placing it on a table in front of him and seeing if Kellen looks hungry.

Kellen glances at the robot, curious, and watches Cynthia bring the box.  He doesn’t know what it contains until she opens it. Once he can see the food, he does look hungry. If he has learned how to ask for permission he’ll do so, otherwise he’ll wait for her to say something.

She points at it. "For you. If you want." It's a quite large portion of curry chicken. It's mild, too, and tastes wonderful.

“Thank you”, he replies, nodding. The food both looks and tastes like the one back home, and is also delicious. He usually avoids meat but he’ll try to tell Cynthia later and eat the curry anyway.

...right. What next. Hmm... Cynthia gets several different sniffers using her phone, just in case. "Kellen", she says, pointing at him. "Words. Learn them with me?" This is awkward, wow. But it's going to be so exciting to find out what happened with him!

Kellen feel pretty awkward too but being able to communicate will be so nice! 
“Yes, words”, he nods, “learn… together?”, he pauses for a moment as he looks for that last word. He feels a bit embarrassed and can feel his cheeks warm up.

Cynthia nods, hoping that Kellen can learn the language well with her help. It's not long during their practice together before the 2 sniffers arrive; Cynthia places the 2 rectangular boxes not too far away from them while continuing to help Kellen learn new words with her phone.

When the sniffers arrive, Kellen gestures at them, curious. “What is?”, he asks, cringing internally at his lack of skill with the language.

They're 2 rectangular black plastic boxes, about as big as a large lunchbox, brought in by Cynthia. They arrived very quickly after she put in the order. "Sniffer", she says, pointing at them. Then she taps the phone over the drawing of someone ill in bed, and then the drawing of a nose, making the noises for those words before pointing at the 2 sniffers again.

He repeats the word, nodding, although he doesn’t understand what the other two images have to do with the sniffers. 

“They do… what?”

"Know if sick". Hopefully the pictogram system manages to explain something as abstract as a person knowing something...

It isn’t the easiest concept to get across but they manage to do it. 
“Ohh”, Kellen nods, understanding a bit better. He guesses that the viruses here will be new to his body.

Cynthia does her best to let the new arrival practice with her; she fixes a setting on the app with the pictograms, so that it shows the text for the given word whenever a pictogram gets held.
