Here's how Kenji and Lazarus explain the reason they didn't tell anyone about their limbs.

Chapter 12: All Explained

At the Sacred Hall of Heroes

Shifu enters the Hall of Heroes and he brought in Lazarus and Kenji for some deep explanation about their prostetic limbs and Lazarus fighured something like this would happen and the fact that he let his guard down messed him up more than anything and to add insult to personal injury, he sees the Furious Five, Po, Musaki and Arizona standing there and as Shifu stepped in the center near the Moon Pool, Shifu stared at the young Huskies and completely grew a little upset with the boys that he never mentioned about them being amputees.

Tigress looks over to see what the situation was about and she asked, "What's going on, master?"

"I just found out that Lazarus and Kenji are amputees." Shifu replied.

Most of the masters except for Musaki were really shocked and stunned to hear this come out and they turned their eyes on their limbs and then at them and Kenji clears his throat and said, "Look at the upside, Laz. At least we're not busted for gorging down gallons of ice cream and that I puked a little yesterday."

Lazarus glares at Kenji for a second and he said, "Not the time for this, Kenj."

"Amputees, master?" asked Arizona.

Lazarus felt that it was time to chime in and he said, "Amputees are those that lost some parts of their bodies; leg, foot, arm, hand due to some accidents or injuries that occur so that those who lost those body parts are replaced with prostetic limbs in order to continue adapting to life."

Shifu stared at them for that insight and he said, "Thank you, Lazarus."

Arizona looks up at the Huskies and he asked, "So...you guys have been here 2 weeks and didn't tell us about it?"

Lazarus nods his head slowly because he was definitely nervous about what the after reaction would be and Tigress really wanted to get to the bottom of this and she said, "And yet you two came here in this kung-fu summer camp because of your limbs?"

Both of them nodded their heads and then Kenji said, "It was actually my idea to...talk Lazarus into coming here."

"What bothers me is that why didn't you tell us that before?" asked Shifu.

Lazarus lets out a heavy sigh and he replied, "I didn't want to tell you all...just until I get to know you better. I was just...just too afraid."

"Afraid of what?" asked Viper.

"Of being rejected. Because of the fact that because I have one arm, I can't do anything." Lazarus replied.

Everyone turned to Kenji to see if he had the same similar concern about it and he only said, "I sorta didn't know whether or not they would let us participate in this camp because we're both amputees. We were kinda hoping it's not a big deal...maybe?"

Soon enough, all of them weren't really that too upset about the fact that they did show up with those limbs and Po asked them, "How'd you guys get to be amplufees?"

Musaki clears his throat and elbowed Po and muttered under clenched teeth, "Amputees, Po. Amp-u-tees."

"Ohhh...amputrees."

Lazarus cleared his throat and he said, "Well, I lost my arm when I was seven after while I was exploring in the bamboo forest in the Valley of Peace and as I'm looking, I noticed that I was standing on a jagged cliff and as I tried to get out, everything sorta came crumbling down and I landed on the ground and a huge rock fell onto my arm, barely missing me but I couldn't move at all. It was stuck and I was really terrified. When my family came to find me, they were afraid that I might've been dead, but luckily they saw me moving otherwise they would've missed me. They tried to pry me out of the rock, but it was no success. My dad made a suggestion that in order to get myself free, he took it upon himself to cut off my arm. We had no other option. I got free, but the fact that I lost my arm...shattered me. For the first few months, I had to deal with the fact that I had one arm and I mostly stayed at my home, moping around and basically asking myself 'Why did I let this happen?'. I just kept blaming myself and blaming myself for allowing this to happen. Then, my parents gave me a prostetic arm in order to help me adjust being an amputee and all. During that time, I've been made fun of by a lot of kids months after the accident and I've been called a 'one-armed freak' or 'Husky one-arm', assuming that because I do have one arm that I couldn't do anything that two-armed people do. So, I used my glove to avoid anyone seeing my prostetic arm as if I still have my arm. But my grandfather wanted to teach me that I can still do anything with that one arm and that I can do anything. Although I still believe what he said, I sometimes second guess myself like...'What if I don't succeed? Maybe I'm not meant to do anything with one arm.' That's why I sorta tagged along with Kenji at this camp...as if it's my only chance to see if I can do kung-fu with one arm. I know it's against your guys' standards, but I really want to try."

After hearing that story, most of the masters were completely awestruck at Lazarus' story and they couldn't imagine what their lives would be without their arms...well minus Viper, but she still receives sympathy for Lazarus.

After this, Kenji stepped in and said, "Yeah, I'm an amputee too. When I was 5...this happened like 4 years before Laz lost his arm, I was wandering through a meadow somewhere in the Southern Region of the Valley of Peace and as I stared at a mountain, I wanted to get closer to it, but unfortunately...I fell down on this hill and I cut my leg. It was like a really nasty scratch and when my parents took me to the hospital, the doctor took a look at it and told me that the same cut became infected and it was spreading through my legs and in order to get it...uninfected, I had to lose my legs. After I got amputated, it still feels weird to live the rest of my life without my birth legs but I was told by the doctors that I was pretty brave to let them cut my legs off...even though I didn't really show it. So, me and Lazzie are the only ones that are amputees."

Silence brewed in the entire Hall of Heroes and all of the masters stared at both of them after those stories were told about them being amputees and Shifu looks at both of them and he said, "And you two decided to enter in this camp despite being amputated?"

"Yeah, pretty much." Kenji answered.

Shifu's eyes began to widen and he felt as if their stories became a testament to overcome personal odds and rise up and he said, "I must tell you boys...that I am deeply impressed."

"You are?" asked Lazarus.

"The fact that you came to our palace and to do kung-fu with your prostetic limbs made us realize that you can still do anything." Shifu added.

The masters were deeply amazed by their stories themselves and Viper slithered over to them and said, "You boys took a huge amount of courage to come here."

"Even when you guys are down, you decide to say 'Screw it, I'm getting up and I can still do whatever' makes me realize that you're much stronger than that." Arizona said, in awe.

"Yeah, I admire you guys for coming in while you're showing your limbs." Mantis said.

Tigress still couldn't believe that losing parts of their bodies didn't stop them from trying out kung-fu or anything in particular and she said, "I may not exactly show it, but I'm deeply touched by your story. The fact that you choose to come here and attend this camp really shows that you're invincible...and maybe hardcore."

Lazarus was a little taken aback by the hardcore comment and he said, "Um...thank you?"

"Tigress, let's not confuse the two Huskies' minds." Musaki added.

Tigress glared at Musaki for a second and she asked, "What? I'm not supposed to be blown away by their trials and overcoming the odds?"

"No. I'm saying that the hardcore part doesn't really apply to them." Musaki said.

Shifu clears his throat and said, "Nevertheless, we're all really proud of the fact that they came here despite losing their arm and legs and we should really commend them for taking it a step further."

Kenji smiled at them and said, "Thanks. And I'd like to say that Lazarus and I had surgery throughout being amputated and I had like 18 stitches on my butt during that time."

Everyone froze for a second after Kenji's little info and all Crane could say is, "Interesting..."

"I still have the stitches unless you guys wanna see it." Kenji said.

"NO!" everyone exclaimed.

Musaki clears his throat for a second and quickly thought now would be a better time to change the subject and said, "Why don't we...start training now?"

"For once, I agree with Musaki." Tigress added.

Musaki dropped his jaw after hearing what Tigress had just said and he said, "Did you guys hear that? She said it! She said she agrees with me...for once! Also...I knew this day would come. I called it, by the way."

As everyone made their way out of the hall of heroes, Lazarus looks at Shifu and said, "Thanks for understanding. I was afraid that you'd kick us out if you found out."

"After a story like that? Are you serious?" asked Tigress, in disbelief.

"Why would we do that? You two are fighters in your own right for going through this and I have to say I see you're gonna make a difference for everyone." Shifu said.

Lazarus smiled at that thought and he figured that going to the kung-fu camp was the best thing that ever happened and maybe it'll help him exude confidence throughout this process.

Now that they told, it seems as though they're finally gonna enjoy the rest of the camp!
