Harvey: Hi, Reggie! Can you give me 5 minutes?
Reggie: Sure, actually I can give you 10min.
Harvey: 5 is ok! Thanks!
Harvey: OK.
Harvey: Ready! 
Harvey: Ahhhhh!
Harvey: Mel has just come.
Harvey: And said she wants to talk to me...
Harvey: Probably extension of my agreement.
Reggie: OMG!
Harvey: That was not planned at all.
Reggie: Ok, let me know when you finish.
Harvey: Ok, I'm back. So sorry!
Reggie: No worries at all! 
Harvey asked Reggie for 5 minutes of his time in order to tell him about Mel. She will probably extend his agreement, so, as it was not planned, Reggie wants to know when Harvey finishes. Harvey is sorry that he is back.
