The burning love flame

Where could he be?

Nobody even noticed at first that Kai hadn't made it back to his room.
Nya went up to Kai's room when it was time to start training, she knocked on the door “Kai? You in there?” as Nya got no answer she just went in.

Kai's room was empty.
That was weird.

“Huh?” Nya said to herself before checking Kai's bathroom and balcony to make sure he wasn't there. “That's strange..” Nya went to knock on Cole's door because his room was right next to her brother's, she knocked. Cole opened the door “Hey, wassup Nya?” Cole asked the water ninja.
“It's Kai. He isn't in his room, is he here?” Nya asked the black ninja. “I'm afraid not. I'll help you look for him.” offered the ninja kindly, the water ninja accepted the offer.
The two ninja called the other ninjas to get more help trying to find the red ninja. Sadly Sensei-Wu was away on a journey of his own so he couldn't help the ninjas.
The ninjas looked through the whole hotel, checking every room and corner they could think of. They even checked outside.
But wait, what was that hanging on the broken tree branch?!
“That's a piece of fabric from Kai's gi!” Shouted Lloyd. Nya was having a small panik attack “Oh no! Where could Kai be?!” The water ninja started tearing up. Jay took Nya into his arms to calm her down. It worked. Nya calmed down but she was still really worried about her brother.
Where is he?
What happened to him?
They started to look around to find any other clues of where the red ninja could be. Soon enough Pixal had found something. “Zane, I scanned the area and I noticed an strange box in those leaves right there.” said the female robot. “Guys, Pixal found a box in the leaves!” said the titanium ninja. The blue ninja rushed over to the leaves and started looking through them, sure enough there was an small cardboard box laying under the pile of leaves. The green ninja grabbed the box and opened it. Inside was a note.
From Morro..?!
The green ninja read out loud what the note said..
“Dear, ninjas. I am back, you can never get rid of me as long as I am not the green ninja, so I stole the most important person to the green ninja, the one and only, the master of fire. If you want him back you'll have to find me. I'll be giving you 24h to find us or your little friend will not make it. Those will be some pain filled 24h for your little master of fire, not as strong as I thought. I laughed right now but you couldn't hear it because none of you even noticed me sitting here, under this same tree writing this letter for you.
-Morro”
Holy sh*t.
The water ninja bursted into tears “We beed to find them! Kai might be strong but he isn't that strong!” “Don't worry Nya we'll find him.” said the black ninja confidentally even tho inside he was really scared for what Morro could do to his partner.
