(Time is irrelevant. Age is irrelevant. Let's just say that Morro is a few maybe at least two years older than the rest kk. Ight, let's go.)
A young boy was training in the courtyard of the monastery.
That was Morro. He was so focused on training that he didn't notice his sensei walk in on him.
"Morro? Morro!" Sensei Wu called out.
"What? Oh. Sorry sensei. I'm just training." Morro replied.
"Don't train so hard. I know were not related by blood but, I want to feel comfortable here. I think of you as a son." Sensei told him.
"O-okay, sensei." Morro said, "is there something else?"
"Well yes there is" Wu started
"Remember my brother Garmadon? He had a child!"
"Really? How have I not heard of this? We kinda live in the same place." Said Morro.
"He has been going out for most of his free time."
"If I'm like your son, then does that mean your brother is like my uncle?" Morro asked.
Sensei Wu's heart felt touched.
"Yes! Yes, of course!"
-time skip-
(Misako and Garmadon visited with Lloyd.)
"Is this Lloyd?" Morro asked.
"Yes, that is. And he's now your little cousin!" Misako said joyfully.
"Heh." Morro played with Lloyd by lifting him into the air with his wind.
"Brother are you sure that Morro is trained well enough?" Garmadon said worried.
"Please Garmadon, do not worry. He is trained and can control His powers well." Wu reassured his brother.
"That may be so, however, Morro is still at a young age!" Garmadon called out.
"Lloyd will be okay." Wu put his hand on Garmadon's shoulder.
-oh, wow a time skip
This time after the battle between brothers. -
Wu stood still in the dark.
"No... No no no no what did I do? Brother..." Wu dropped onto his knees
"I- I'm sorry I didn't... AAAAAHHHH!!"
"Sensei!" Morro said sliding the door wide open.
"What happened-" He found his sensei on the ground.
"-here..."
Wu grabbed his pupil and hugged him tightly.
"Sensei?!"
"Morro, stay here for a bit. I'll be back." Sensei said.
"What happened to Garmadon? What about Misako and Lloyd?" Morro asked.
"They'll be fine." Sensei Wu replied eyeing the golden weapons.
"Oh. Then, I'll... Be here. I guess." Morro said dropping his tone.
Then Wu left with all the golden weapons of spinjiztu.
