Mixing genres - YA and SciFi

YA isn't a genre. There's a lot of YA SF. And read the stickies.

BTW, don't post first drafts in the SYW section. At least you didn't. Before you do, if you do, edit well to remove any foreseeable mistakes.

I'm a bit confused. What are you looking for advice on? Are you asking if this conversation will affect the classification of your book?

Your book is only Young Adult if the book follows a young protagonist and includes themes attributed to the young adult classification. One conversation is not going to affect whether or not your book is classified as Young Adult.

Additionally, "Young Adult" is not its own genre. You can write a book that is YA Science Fiction. The two concepts aren't mutually exclusive.

Does this information address your concerns? Or am I way off base? I know you said you don't have a specific question, but perhaps asking one would help us assist you further.

Young Adult is a category, not a genre. So, just as you have adult SF, you can also have YA SF. I'm also confused about what you're asking. Is this an adult novel where the only teenage character is the one having this conversation? Or is the book YA?

By the sounds of it, you have a science fiction novel with a minor teenage character. It's not YA based on what you've described. There is YA science fiction (a lot of it), but that doesn't seem like what you have.

If you have more questions, you can always post a small excerpt in the Sandbox. Like Share Your Work, it's password protected, and the people helping out in there don't expect it to be polished just yet.

I think the question is with regards to the vernacular of language spoken by young adults/adolescents. I read it that this is asking for our help with this, knowing that since we write YA we are familiar with the particular nuances of this.

I'm thinking if you shares the excerpt in the SYW with another question relating to this you will get the info you needs. I will say though that the discourse between adolescents and their parents may have some differences depending on cultural origin, although there will probably be some general things in common.

Perhaps you could read a few YA books focusing specifically on this. If you tell us more about the kind of relationship you want to build between your two characters I/we may even be able to direct you to some good examples to suit your needs.
