To have a word

Finn: Welcome to The English We Speak, I'm Finn and I'm waiting here in the studio for Feifei, who is late—again. I'm really getting fed up with her. I think I'll need to speak to her about this.
Feifei:(Door closing) Hi Finn, sorry I'm late. You know how I love crosswords? Well, I was just doing one, and I forgot the time ... 
Finn: We need to have a word, Feifei.
Feifei: We need LOTS of words, Finn.
Finn: What?
Feifei: To complete a crossword successfully, we need lots of words.
Finn: No, I'm not talking about your crossword, Feifei. I'm talking about your lateness. When I say 'we need to have a word', I mean we need a short, serious discussion about this sensitive topic.
Feifei: Oh, I see. You're upset that I'm late, so you asked me for a word.
Finn:That's right. Here are some examples
Feifei: OK, Finn. I understand. I'll make an effort to be on time from now on.
Finn: It's always better to have a word than just get angry.
Feifei: Yes, you're right.
Finn: Good. Shall we get on with the programme, then?
Feifei: Well, actually Finn, I would like to have a word from you too.
Finn: A word with you. The expression is a word with you.
Feifei: No, no—I want a word from you, Finn. You see clue 6 in the crossword is so tricky!
Finn: Feifei, I don't want to do your crossword!
Feifei: Oh just this one clue! It's an animal with ... five letters. What could it be? A horse? No ... 
Finn: Look, Feifei. I'm going to need to have another word with you! We need to record the programme!
Feifei:Donkey? No that's six letters ... 
Finn: Feifei, come on!
Feifei: Maybe it's a whale?
Finn: Stop it!
Feifei: Giraffe? No.
