Harumi apologized to Lloyd and his friends/Encountering Mr. E

Here is how Harumi makes up with Lloyd and his friends in Son of the Overlord.

Harumi then wanted to speak to Lloyd and his friends, she felt sorry for her cruelty.

Harumi: Lloyd, I'm really sorry for everything I've done in the past. I have no excuse why I was the Quiet One in the first place after my parents were killed, I hope you can forgive me.

Lloyd Garmadon: (smiled) I already have. (to his friends) Guys?

Kai: Yeah, I guess we can trust her again.

Cole: If Lloyd trust her, it's good enough for me.

Jay: I don't see why not.

Nya: Sure.

Zane: We may not have any choices.

Skylor: She's one of us now.

Li'l Nelson: And this time, it's gonna be different.

Ken: Not to mention in a unique kinda way.

Harumi: Thank you, I promise I'll make it up to you all.

Lloyd Garmadon: I know you will.

Then, they heard a strange noise coming from behind the bush.

Jay: What was that?!

Zane: I'm detecting a strange reading.

Then out of nowhere, Mr. E appeared and attacked.

Harumi: It's Mr. E!

Then, he was about to attack Lloyd as Harumi stopped him.

Lloyd Garmadon: Harumi?

Harumi: See, told you I wanted to redeem myself!

As they both nodded, they started working together to stop Mr. E as Arnold the Cyberman snuck up behind him.

Arnold the Cyberman: Initiating stopping Mr. E!

With quick thinking, he buzzed out his circuit out cold.
