Crystal lives a fairly ordinary if hectic life as a fifth grade teacher at Jefferson elementary school. The kids are as well behaved as kids ever are and her colleagues are nice. She is very much not expecting anything of the sort when she steps between two trees on a weekend walk and abruptly finds herself somewhere clearly different.
It's a different pair of trees. A pair of trees inside of a pretty garden, with tons of flowers across a small pond. There's a small group of children walking around, maybe 10 year olds, maybe half of them in school uniforms, with girls and boys both dressed in white skirts and professional looking black sweaters, like those used in British school uniforms. The weather is sunny and warm, but it's a dry heat, so it's just pleasant and not muggy. There's a woman, presumably the class teacher, walking them around the beautiful garden. There's an inviting forest surrounding the garden.
She wants to scream. There are kids so she restrains herself. She pulls out her cell phone and desperately hopes it has signal. It does not. She looks around for a bench to sit down on.
There is one a few feet away from the pond. It's made of some kind of black plastic (presumably) material instead of wood, and it actually feels quite soft and comfortable to sit on.
The adult looks at her in confusion, but doesn't say anything. People who need help would know to ask. Instead, she turns to the kids, talking about how the flowers they're seeing today are the results of many hundreds of years to make them as beautiful as possible.
She gets herself more together and listens to the lesson. She's reluctant to interrupt, maybe someone else who isn't busy will come by.
The teacher looks at her for a moment before continuing her talk.
"These flowers have the colors they have due to recessive and dominant alleles. In essence, you can have strong allele that overpowers the weak one, or a weak on that loses to the strong. This white color is strong, and this purple color is weak; one white can beat one purple, so the purple color only shows up if there's no white color overpowering it. In people, there's a very severe illness, that everyone can get on X-chromosomes. But it's a recessive genetic illness. In women, their healthy X-chromosome can "beat it", so they don't get sick, but in men, they only have one X-chromosome, so if they get that illness, there's nothing to fight it back. Actually, one country had a queen with illness allele who gave it to her sons but not daughters, so the country got lots of queens because the kings died of the illness!"
That's an unusual way of framing that information. She's not one to interrupt a fellow educator though, she might ask about it in private but not in front of the kids.
Eventually, the teacher turns to Crystal.
"I haven't seen you before! Are you here to enjoy the pretty flowers and ponds, too? Or even try diving to find some of the sunken treasures?"
"I don't actually know where I am or how I got here and my phone doesn't have service. I'm having a rather alarming day." Through this all she keeps her voice carefully steady.
"What happened? Do you think you have amnesia? Can I see your phone?" The teacher doesn't hide her shock particularly well, but tries to act as reassuring as possible for Crystal.
"I don't think I have amnesia... I was walking through some woods and then suddenly I was here. And these flowers and school uniforms are both unfamiliar. Here's my phone." She takes out her Pixel 6.
The teacher looks at her phone. It doesn't take her many seconds to realize it's not of thomassian make; somehow, a genuine teleporter from another dimension is in front of her. She rapidly dials a number. "Hi, Pandemic Awareness Day came early this year. Tell everyone from Heaviside Arboreal Boarding School that a person has teleported from another dimension, potentially bringing an infectious illness. This is urgent information."
"Excuse me, but what's your name? My name is Clarissa. You must feel so disoriented, but don't worry; we're here for you." She subtly gestures for the children to keep their distance from the woman sitting on the bench.
"Oh. This isn't just another city. This is, oh. I'm Crystal, Crystal Miller. And I'm not getting home soon am I?"
"I wouldn't know that, you shouldn't ask me! But don't worry; we'll be here for you. We'll have a room ready for you by the time we get to the school, trust me."
She motions for Crystal to follow her, as she slowly begins the walk back through the spacious canopy of trees, brightly lit by the sun.
Oh right they mentioned diseases... She will take the N95 mask in her pocket out and put it on. Maybe that will be important. She gets up and follows the teacher.
After 20 or so minutes, they reach a school building that seems to be maybe 8 or 9 stories tall? At least weirdly tall for a school building. Clarissa looks at her phone, before leading Crystal into one of the dorms on the ground floor. It's a reasonably spacious room, with a thick, soft carpet and a small bathroom. It still has 2 upper bunks, above the soft carpet.
"This is where you should probably stay for the quarantine period. We're hoping to convert a nearby room to a medical facility fairly soon; don't worry about a thing."
"Well, we'll send out a swab in case you actually have a virus that's dangerous for us but not you, so we can get a head-start on developing a medicine. And I'll have to stay with you at this point, too. I worry that we'll have to go through the full 10-day quarantine, unfortunately."
"I don't think they could do that in my world. Is it really a good idea for us to be staying together we basically spent half an hour outside together I wouldn't expect you to catch anything from that or vice versa but ten days in close quarters seems like it would effectively guarantee we would get sick if it was going to happen." She pauses. "Unless that's the point."
"Well, yeah... I'm kind of expected to be the one taking one for the team, here. For all we know, I'm sick already. So why risk someone else? Anyway, you sound distressed... I can change into some real PPE and give you a hug, if that makes it better?"
"Uh... you're also risking me and I didn't get asked about that. I don't know why you're being so blase about this but I definitely didn't sign up to get some weird disease that you already have vaccines for."
"Sorry, sorry! I can happily let you quarantine by yourself. It's just... well, I think we'd both probably have to find out, eventually."
She takes a deep breath and steadies herself. "I would really prefer that. I'm okay with being quarantined for longer if that means I get vaccines or whatever else that makes me less likely to die of something that could have been prevented. Assuming, your vaccines are even safe for me to take. I don't know how we're speaking the same language or why we look so similar."
"Well, I guess we can get you vaccines? We just haven't needed them for a while, just because we did such a good job of stamping anything that might need them out. All the vaccines we have are kept in storage, just in case they prove useful. I'm hoping they'd be safe for you, just because we look so similar and even speak the same language. But the separate quarantine thing... yes, I'll 100% walk off and leave you by yourself. To... keep you safe as well."
