They will still probably distinguish by days because it’s not like the housemates will be wearing the same clothes. Unless it’s just close up face shots they edit in.True. They probably should just say every episode.
I probably shouldn’t keep comparing to Survivor... but they do say what day they are up to and it doesn’t matter that one ep covers three days. I get that there are different expectations for BB, but new fans / viewers won’t know any different.
