My explanation for harumi feelings
Crystallized has revealed that she jas feelings for Lloyd
But she has tried to kill Lloyd multiple times
That's why a lot of people believes that harumi feelings for Lloyd was out of character
But in sons of garmadon harumi offered Lloyd to join the sons of garmadon
Which means that she probably has always had feelings for Lloyd
But that make her more evil
Because just think about all what she has done to him and she is supposedly in love with him
And at the end of crystallized she didn't save Lloyd and her third adoptive father untill the overlord revealed that he is the one who corrupted the great devour
She has no problems with letting the man she love ( according to crystallized)
Skylar also was evil but her lovefor kai changed her
So in other words harumi loves Lloyd but she has no problems murdering him
And it's not asa strong as how the other girls love their partners
Because she is selfish
I mean even nya will die to save jay
