Hawk Moth was failing, the Miracle Team have him surrounded.
In desperation, Catalyst rushed out of the attic, opened the safe and took the Peafowl Miraculous.
She didn't need a reason, she just broke her tablet containing the Akuma and let the dark energy expel from it as she changed back.
After becoming her normal self, she opened her fist with the Miraculous in it.
A blue orb of light started to emit from it, flying into a frenzy, then dimmed down, revealing the blue Kwami.
Her eyes rose to see Nathalie staring back at her.
"G-G-G-Greetings, I'm D-D-Duusu. Your K-Kwam-m-mi." she stuttered
Not out of shyness, be from being unstable.
"I'm Nathalie, but there's no time for introductions. You have to transform me."
Duusu shook, "I c-c-can't, my p-power has been d-damaged. If you t-transform, you will-"
"I DON'T CARE!" There was a short silence.
Sorry, Duusu. But I need to use you power so we can have a fighting chance. Please Duusu, do the right thing."
The Kwami saw fear and love in her eyes. Empathy washed through her, she took a deep breath before speaking.
"S-Say 'D-Duusu, Feath-thers Bloom."
Nathalie sneered, "With pleasure. Duusu, Dark Feathers Bloom."
