C'mon thats not why, if that was the case they could have used Blairs restroom, no audio there as well, they clearly do something else. or they can whisper like they do all the time anyways and with the music you wont hear anything 🙂
Always the same songs playing in b4, wonder what they are getting ready for, sure takes a long time. Girls on their phones looking all the time texting or whatever.
Bit annoying that we can't see the porch right outside the door from the kitchen, they should have placed the pool cam 2 in that direction, but somehow they don't want us to see any parts of the house from outside.
