I’ve Been Playing Crk For About 6 Or 7 Months Now And I Still Don’t Get What Happened In The Final

I’ve been playing crk for about 6 or 7 months now and I still don’t get what happened in the final battle. Was the explosion caused by Pure Vanillas and Dark Enchantresses power compined or was it Pure Vanillas power alone?

I mean it does make sense that it was their power compined considering that we never see Pure Vanilla doing something like that again. But Hollyberry was crying in that scene and it seems kinda out of character for her not to have faith in her comrades, unless Pure vanilla has lost control of his powers before, causing a minor explosion?

But ig Hollyberry could just be emotional because he was sacrificing himself.

Anyways, could someone plz explain this to me 🙏
