THIS CONTAINS A SPOILER FOR THE GAME.

The game was absolutely amazing but one issue leaves me with a question. We can theorize/infer from the previous game that Hedron is just a physical living being used by a resonance entity to boost/amplify it's resonance/frequency. Polaris was using the Hedron in Control to amplify it's frequency to keep the Hiss contained in Slide scape 36 and that Polaris wasn't Hedron. Killing Hedron didn't mean the death of Polaris, it just got weaker then she found a new amplifier/Hedron which is Jesse. So why did the resonance in Resonant completely die when Dylan killed the Hedron which is just it's physical amplifier?
