Every year on his birthday, Dean's put the same set of plastic balloons on whatever form of birthday cake he has. He's gotten pretty sick of the stupid balloons by now until he finds out where his brother found them -

- where did Dean find them? And why does he insist on those silly balloons after all these years?

So it's not super waffy - unless you can make it waffy.

Wincest is fine, if the adopter of this plot bunny is so inclined.
