These are all quite acceptable to her.  (She eats the pickled vegetables second-to-last and much slower than everything else.  The egg she saves for last.)

Eventually Ren gets off the phone. "They're going to find you a social worker who speaks English and is used to strange dungeon-related situations," she says. "But it doesn't seem very likely, if you remember being from a continent we don't have on Earth, that we'll be able to get you home to wherever you belong. Do you have an idea of what you would like to do with yourself, Kennedy?"

"Umm.  I would like to remember who I am?"

"Yes, I'm sure a psychic esper will do their best, but if it doesn't work?"

"Um!  I guess if it doesn't I will keep thinking I am right about where I'm from, and, umm...."  She's kind of wibbly.

"- you don't have to come up with an answer right now, dear, but the social worker might ask. Espers are very busy and it may take a while to find one who can give it a go."

"Yes, - Swan-san.  Do you think if I'm from somewhere else, I may ever be able to go back?"

"Well... more espers awaken all the time, and people figure out new things about how to use the magical things they harvest from dungeons all the time too. Right now, we don't know how to go to any other worlds, though."

"Then I don't really know what I could want to do, Swan-san."

"Well, do you want to learn Japanese and live in Japan, or do you want to try to live somewhere where English is spoken, for instance."

"I have acceptable marks in my foreign language study.  ...I remember."

"Does that mean you would be all right learning Japanese?"

"Ummmm.  Yes."

"That's good to know. I see you've made a great start there, I wasn't gone very long and you've got lots of practice already."

"Thank you."

"- you know, I bet that if Haru were suddenly teleported somewhere he wouldn't want any hugs from strangers, and I bet he didn't offer you any for just that reason, but just in case you're not much like him that way, would you like a hug?"

"- Yes, please."

Ren hugs her. She is good at hugs in a kindergarten teacher way.

There is now a fairly clingy eight year old on her!  For perhaps the foreseeable future!

That is so understandable and she timed this to allow for that!

She sniffles, and startles a bit before carefully releasing Ren from the hug.  "Excuse me."

And she makes for the bathroom.

Also so reasonable.

She emerges twenty minutes later, looking uncryingly pristine but shuffling more than walking.  Probably the two of them have started doing something else and she needs to evaluate it.

Ren is unpacking. Haru is studying Japanese but drops it as soon as she comes out to stumble into the bathroom himself (he crashes a bit into the doorframe but calls "大丈夫" to his mother before continuing into the bathroom).

Kennedy supposes she should continue studying Japanese as well.  After a pause, she stops shuffling and walks over there normally.
