I'm sorry for this one.

August 24, 2018 (night)

After Garmadon was arrested, the ninja ad their allies gathered around town square. "Ok, where is Ash and the twins? They're obviously here somewhere." Kai said. That was when Nix came running and hid behind Wu. He then grabbed the sensei's shield and was on guard.

"Acronix, what's wrong? Where's Ash and Krux?" Zane asked.

"I don't know, but keep Ash away from me. She wants to clap my cheeks and she hits hard." Everyone rolled their eyes. Ash then came running towards Nix. He sat down and Ash immediately stopped in her tracks with a smirk.

"You can't sit forever. You'll have to stand up eventually." Ash pinched Nix's cheek(the one on the face cuz Nix is sitting) and walked away. The twin got up and ran to his brother.

"Krux, don't let Ash near me. She wants to clap my cheeks."

"What does that even mean?" Krux asked. He got his answer when Ash walked up and smacked his ass.

"Nice cheeks handsome." Ash told Krux.

"I should have known." Everyone got some rest before rebuilding the city.

Krux is young.

And BOOM! Young Krux. Screenshot from Google.
