Aparentemente nada fora do comum
Não é o melhor exemplo, mas há apenas um exemplo em que realmente posso pensar que se encaixa no projeto, no livro 19: The Departure. Um Yeerk infesta Cassie enquanto ela está a meio caminho de se transformar em lobo, então ela se desmorona. Não é completamente em uma metamorfose, mas ainda não é o corpo normal do hospedeiro.
"I would if you weren't in her," I said. I began to morph, as fast as I could, back into the wolf.
...
<I'm giving this Controller a place to go, so we can hear from Karen.>
With my half-hands, half-paws, I grabbed Karen's head and pulled it to me. I pressed her ear against mine.
"Nooooo!" Marco screamed.
But there was nothing he could do to stop me. I was a wolf. He was a human. Already I could feel the tingling touch in my ear.
Cassie demorphing não é mostrada explicitamente, mas ela logo toma um novo metamorfo, o que significa que ela deve ter se demorado em algum momento.
And then, I felt Aftran opening a specific memory. I felt her causing me to focus and concentrate.
As she herself aimed my eyes, I saw the gray, feather patterns begin to appear on my skin, like drawings that slowly came to life.
The Yeerk spread my wings. And she flew.
