[Oh Steve. Sit back and watch.] Hey there, Joy. [He gives a polite smile.] I'm Isaac. I've been stuck here for a while too, I know that it's scary but you're going to be alright, I promise. Even though we're all strangers here we're still kind of like a big family because we've all went through the same thing, so we all know what you're feeling right now. You're a lot calmer than I was when this first happened to me, I'm impressed.
[He saw the hearing aids, and Isaac is making sure that he's looking directly at the camera as he speaks because he doesn't know how well they work. He isn't, however, raising his voice, because he doesn't want her to think that he's assuming she can't hear.]
Don't worry about your mom right now, I know that's hard but Steve is right; she's not going to notice that you're gone. You're there at the same time as you being here, it's some stupid science stuff that I'm not really into, but we can have someone a lot smarter than me explain it to you if you'd like.
