During the geology discussion she keeps making references to her world's 'technology', and how certain kinds of rocks are used for this or that. It sounds more like magic than technology, but she seems to understand it just as well as an engineer knows thermodynamics. She even complains that she doesn't have her reference material.
Well the point was to give him a sense of the technical vocabulary, not to have a grand exchange of knowledge in physics and magic. Is that goal now accomplished?
Yes, much of it is. He's been typing happily away at his computer and comparing things and making comments about the roots of the words she uses and asking some questions about how they're formed and which parts were created or evolved naturally, though he has good guesses about those after a while.
She's getting bored of this. Another's excitement is only contagious for so long. She asks to switch to a brief explanation of that merfolk language, then wonders aloud whether the Protectorate has organized a list of things she can rebuild on that ruined island yet.
Harry isn't too disappointed that she gets bored of his excitement, he's pretty used to it. He has collected enough material for a first version of the translator to start being made, probably, and informs her and a PRT officer about this, as well as asking about things to rebuild. The PRT officer tells him something, and he tells her that Legend will be here soon.
The magical feeling of understandingness Harry has is definitely absent here, even if she knows all the words.
"You don't have to tell me about it," sighs Legend. "The Sentai Elite are saying they have a claim on you because you slept in a mountain in Japan."
"I made that mountain. Complain about changing the land? I saved half. Tch."
"Truth is they probably want you on their team and think we stole you from them to have your powers."
"I can see why they think that. Take me here before I know much about what happening. I want to talk to them, fix island, maybe if they ask instead of yell at me I join. More earthquakes to stop there."
...it is pretty clear that he doesn't think much of people who bicker over politics when their country has been almost destroyed by a giant monster.
"So, Japan soon. What now?"
"I'm not sure. I'll contact Japan when we're done here, but we need to know the scope of what you want to help with so we can properly direct you." He seems to have either forgotten she doesn't exactly speak English very well or decided that she'll learn if he just speaks.
She frowns. "Stop earthquakes, yes. Build thing, yes. Get diamond and steel from rock, yes. Stop villain? Okay, villain needs stopping. Patrol just in case? Boring. Make speech and impress people? Boring."
"Hmm. Well, we will definitely tell you about major earthquakes we learn of ahead of time. Getting raw materials isn't actually very hard for us, but if you're feeling bored you can help with that. I'm curious about what things you can build, and how nondestructive you can be when dealing with villains."
"I can fix the... Under part, of your roads. Not the top. I can do building from stone and concrete. Can do... Pipes, but not wire. Can fix weak tunnels, easy. About villains, should I show? Spar?"
"We always welcome help against villains. As for the rest... much of that is done by the government, so your doing that would be actually very welcome, but it would also need permission."
