My favorite thing about A Very Potter Musical is that Professor Quirrel deadass just walks around with a guy just pressed up against his fucking back like “nope, no voldemort’s here, just a regular dude who happens to have a person sized growth on his back”
What if The Cube represented the tight knit family?
In the beginning it started out intact. As the show progressed and we learn about Marvin, the cast kept taking pieces out of it and rearranging it, representing the fact that this family was changing and being torn apart by everything.
At the opening of act 2 the blocks were all assembled, then as Marvin sings “it’s about time” they collapsed and the cast tried to fix them so they would be comfortable sitting around the blocks. Maybe this represents that the family doesn’t have to be perfect, that everyone had to make their own little tweaks in order for it to work out for everyone. That the family needed to experience breaking before it could be “fixed”.
Then as Whizzer dies, he turns his back on the audience and walks toward the back of the stage as two parts of the cube come together and close in front of him, forming the same cube from the beginning of the show. Mendel and Jason later take out a single block which becomes Whizzer’s headstone.
So now we have the same cube, but with a single piece missing. Whizzer’s death brought the family together; Trina and Marvin, Marvin and Mendel, Charlotte and Cordelia with the rest of the family. They were finally able to support and love each other unconditionally, but at the price of Whizzer. Most importantly, they all felt the loss. Every person mourned Whizzer’s death, and this tight-knit family was essentially brought together through the loss of a very important person in that family.
Whizzer is the reason everyone became so close, the reason The Cube was a cube again by the end of the show, BUT ALSO the reason why the last time you see the cube it’s missing a single piece. Whizzer is that piece that everyone lost that day. Although the family is together they will never be complete.
