Right through Grimm season two, I was thoroughly confused by Nick sleeping on the couch. They have quite a large house, so how is there room for only one (relatively small) bedroom upstairs?
This is a common TV Trope known as Exiled to the Couch. The man has to sleep on an uncomfortable couch instead of a bed. Even when circumstances should allow him to sleep in another available bed.
The real life house that was used in the Pilot which Nick and Juliette supposedly live in has 4 bedrooms.
There are different options (why he sleeps on the coach)
- The Grimm wanted to sleep on the couch because a different bed would make it(problems with girlfriend) real.
- They don't have a bed in the other room(s) or the rooms are offices/ full with boxes.
There are two bedrooms and two baths in the first floor. Nothing more. The ground floor has kitchen with door, garage with door, "sitting room"/room with THE coach, PC (later) and perhaps more.
I want to thank the real house (4 bedrooms) and episode thing. I search for a room number.
