Quantum Uncertainty
Wherein our dance moves become unpredictable.
It turns out that, due to the nature of quantum fluctuations, every time our dance instructor, Mr. Jenkins, steps on his left foot, there's an alternate timeline where he steps on his right.
It's a real challenge for him to keep up with his own footwork, let alone our own.
And so, we find ourselves in a realm where every step forward creates a new reality, and our dance moves become the fabric of the multiverse.
