mistakes during the filming

In one of the later episodes IP, who is tired asks "Trine, make us some coffee".

The actress Trine Pallesen whose character name is 'Gaby' looks at him with surprise and says "Trine????"

IP, not realising his mistake just stares back at her as if to say 'yeah so what's your problem?'

All the other cast members kind of look at him strangely for a moment and then get back to the story.

The directors had the sense of humour to leave it in.
