All the hugs
Cryptor was getting on his last nerves (or was it wires?). Whatever it was, Cryptor was not pleased with the albino stone army general.
Now that the stone army was gone and he was no longer needed for fighting purposes, Kozu had tried to become like a human teenager. Even if he had extra limbs and could hardly speak English correctly with his heavy accent and lack of knowledge of the English language. Though he spoke it pretty well compared to have having little contact with the people of Ninjago.
Also because the Overlord told him to stop moping around and do something with his life so he thought he'd try to adjust to all the computers and technology. Which meant trying to be a human and then that was already explained.
Back to the topic of Cryptor. Since robots did not have emotions and he certainly didn't, he did not understand why Kozu was 'obsessed' with him. The Overlord (happy that his child was doing something at last) had loudly explained that it was called love and he had to deal with it or he would be melted for hurting the embodiment of evil's baby.
The Overlord just really loved Kozu as a son and even a robot such as himself could understand that.
But he missed out on part of it because he was highly disturbed by Cyrus' body flopping around and he guessed that what he had missed what's about what Kozu was doing right now.
"Get off of me this instant, General Kozu. Do not attack me."
"Not attacking, called 'hug'."
"A hug?"
"Yes."
"What is a 'hug'?"
"I TOLD YOU WHAT IT WAS WHEN I SPOKE TO YOU, YOU WORTHLESS PIECE OF METAL." The Overlord shouted, overhearing them. "YOU ARE SUPPOSED TO OBEY MY EVERY COMMAND AND IF YOU KEEP IT UP LIKE THIS I WILL DESTROY YOU."
"I understand, Overlord."
"GOOD. NOW GO RELEARN EVERYTHING I TAUGHT YOU NOW OR ELSE."
He nodded, taking in the command. The crab-like robot the Overlord possessed scuttled away, no doubt to go spy on every corner of Ninjago from the top of Borg industries.
"General Kozu, let go. I must go and do as the Overlord instructed."
"I part of learning."
"Fine. But do not disturb me."
"That is point."
"I really do not understand this. Let me research and then you can continue... to 'hug' me." He shoved the stone warrior away and went off to find a computer.
-after lots of research-
"So, we are doing a human custom called 'dating'?"
"Yes."
"And according to my research that means that a 'hug' as it is called, displays affection and warmth."
"Yes."
"Then I suppose since it is what we are supposed to do, that you may continue to 'hug' me. AS LONG AS YOU DO NOT CRUSH ME AS YOU ARE DOING NOW."
