Just saying dude, Mistake actually has a higher chance of being alive than Harumi, because we never saw what hapenned, they never said that she died, and there is also the fact that she is a full-blooded Oni, while Garmadon is just a hybrid, which makes people doubt that she can be killed so easily by him . Although, I also think she is dead, I think she had a bigger reasoning to be kept as Unknown than Harumi.
