I had to go back and check. Your referencing the time skip at the end of "unity makes strength episode 3" right?
WOW, that was so subtle that I thought it was outside my house. That's freaky, I can't tell if they are watching a movie or not. You can hear a car horn honking as the scene starts. Weird.
There is supposed to be a balcony in the sitcom set room. Maybe she included sound effects. But still weird.
Wonder if every time skip potentially has a secret story.
