Throughout motion picture history scientists have been portrayed as scatterbrained. And Chris Pennock excels in it. But perhaps the potion has affected Cyrus in such a way that he lusts for Maggie, even though he is engaged to Sabrina.
I hope not. Why? Because I hate it when stories or story elements turn out to have
no meaning. Then my soul's time has been wasted. I'm not altogether sure that my soul is immortal, so time's sort of an issue. If the Mag-lust is merely a biochemical hiccup, something that has nothing to do with anything Cyrus thought or felt previously, then the current actions of the Cyrus/Yaeger conglomerate are just plot, just "stuff that happened", just stuff they thought up.
