Although the girl didn't seem to care about it, the fire creature was not discouraged. It floated around Hela, constantly chattering.
After all, she had no power to drive it away, did she?
It was even more powerful, so Hela could only accept its existence.
Just as when it was inside Hewitt's body, it had to endure the fact that it coexisted with others. Although it seemed like it was an alien object invading Hewitt's body, after all, Hewitt was outside, and it was inside.
But the truth was that Hewitt was like a parasite to it, slowly draining its power and vitality. If it were on a human, he would almost be savoring his different parts bit by bit, first frying the liver, then roasting the tongue, and then chewing the eyeballs.
An uncomfortable feeling, but compared to that deeply engraved hatred, this irreverence was acceptable. Since he treated himself that way.
So there's nothing wrong with treating this child the same way, and at worst, they'd be even.
