Bloom and Lord Darkar in “Unfinished Business”

I am not like you! I'll never be evil!

That's what our friend over here said too. Avalon used to be a cloud spirit and now he's on my side. You will be on my side, too.

I have a good heart! You can't turn it dark!

Cloud spirits are the purest beings. If I can convert a cloud spirit, I can change anyone. And that includes you, Bloom.
