Question: Has the mother been cast yet? Also, does the film crew know who the mother is already?
Chosen answer: She was finally shown at the very end of the last episode of season 8, continuing into season 9. The actor's name is Cristin Milioti: http://www.imdb.com/name/nm2129662/.





Suggested correction: Many people buy another toothbrush to take on trips and since they were supposed to be going away, they probably decided to use them at home, as if this was their trip.
The whole point of the mistake is they say they have always shared a toothbrush. So why would they use separate on a trip?
