First of all, the cast is great! Jane Levy is especially refreshing. I look forward to this. I love all of: high tech, great singing, and intriguing soul transmogrifications. Extremely clever concept ties it together. Even the choice of music resonates with me.
Here are some ideas bouncing around in my head (maybe writers are listening):
1 - What would the perfect synchrony of a multi-soul sound like? Perhaps a combination of brilliant 5+ part harmony, perhaps jazz improv with unheard of coordinated changes.
2 - What better metaphor for soul/bodies than software/hardware?
The tech consultant should check out NVIDIA's latest and greatest - GPU's with 3D memory and many thousands of simultaneous coordinated cores, running ONE program ("kernel").
3 - I'm a physics buff as well. Some of the proven weirdness of Quantum Physics entanglement operates as if a single higher dimensional entity intersects our space in multiple, quite distant places, causing them to act together with coordination faster than the speed of light. (no joke).
4 - Which gender enjoys sex more? - This show is all set up to answer that! It gives new meaning to the intimate suggestion, "Let's switch positions!"
5 - Do entangled souls always trace back in spacetime to a common creation point (like entangled particles), or are they formed by multiple fusions of initially separate entities?
