I've noticed nearly every Bluey episode has parallel stories. I think this is part of what makes it so entertaining for adults- kids are excited by the obvious message, while parents who need more to keep them stimulated enjoy watching the threads interweave. The writing is simply the best.
The 153rd episode is scheduled for April 14 and many believe that it will be the end of the show in its current form (more on this later).
Measurably increased my stress level ... :(
