Olga: What are you doing here, guys?
Emily: We've been visiting my friend Jane. And what about you, Grandma?
Olga: Oh, one of the doctors, whom I've known for ages, has just phoned me and asked for help.
Mark: What has happened?
Olga: A Russian lady and her son came to the hospital this morning. The boy is very ill, but he and his mother can't explain anything. I have come to translate for them.
Misha: I can help too.
Rob: We'll all go.
Olga: Thank you, but I don't think it's a good idea. I can't take all of you with me.
Emily: Grandma is right. Let Misha go with her and we'll wait here.
