It is now time for Chapter 4. Nigel is tied up in the Teenagers Headquarters and a guard has been sent in, Nigel wonders if it's Numbuh 4.

The guard looked like he had seen a ghost, "What did you say?" The guard asked.

"Wally, I know that's you."

"Sorry, I don't know anything about a Numbuh 4."

"Wally, It's me, Nigel Uno."

The guard looked at Nigel's body and said, "I'm sorry mate, but I have to do this."

Nigel starts cringing as he can feel the gun being pointed at him, then he hears a shot. Nigel is... not hurt, he can actually move his arms and legs. Wait did the guard shoot the ropes off of him? Nigel then takes off the cloth covering his face and looked at a Teenaged guard turned around, he was medium height, had blonde hair, and was looking down.

"Wally... It's me... It's ok."

Wally then turns around to look at Nigel.

"It is you, Numbuh 1."

Wally then hugs Nigel, then Nigel has a wondered look on his face.

"Wait, how do you remember me? You were decommissioned."

"Well... I kinda wasn't."

"What happened?" Nigel asked

"We don't have time right now, listen, I'm gonna get you outta here. Just stay here and I'll take care of the guard outside."

Wally then walks out of the room and Nigel can here them from inside the room.

"Did ya take care of him?" The guard said

"Yep, it was a pretty messy one."

"Well, we better get going"

Then a giant thud as Nigel could feel something, or someone, hit the ground.

Wally then opens the door back up and says, "Alright, let's go."

As they start walking through the halls, Wally is on his phone, "Message to Abby, Message to Abby."

A voice responds, "What do ya want this time Wally?"

"Listen, Abby you're not gonna believe this, but I've got Numbuh 1."

A slight pause then Abby starts laughing, "Wally, have you been eating the cafeteria food again?"

"No, I'm serious, he's right here."

Wally hands the phone to Nigel and Nigel starts talking.

"Numbuh 5, it's me Nigel."

He hears Abby gasp through the phone and she responds, "Numbuh 1... What, What are you doing here?"

"I'll explain later" He hands the phone back to Wally,

"Listen Abby, I'm bringing Nigel over to your office to keep him safe."

"Abby'll be waitin'" A she hangs up

"Alright, Abby's office is around this corner"

But Wally then turns into the same old Wally and doesn't check around the corner, he walks right into two guards who see him and the intruder. The two guards immediately start firing, as Wally fires back.

"Nigel, Abby's office is inside that black door on the right, you need to get inside."

"And what about you?"

"Ah, I'll be fine, I get into this kind of stuff once a week."

Wally then distracts the guards so Nigel can sneak passed them unseen. He enters Abby's office. He looks around and sees a black chair turned around.

"A-Abby?" Nigel says

"So, you really are here." Abby turns around with a smile on her face

She gets out of her chair and runs to hug Nigel

"So, why are you back on Earth?"

"I was going for decommissioning when we were attacked by, well, you guys and I was sent back to Earth on a ship, I've spent months looking for you guys. And I found you here."

Nigel goes on, "Now you tell me, why are you here, why do you have an office inside of the Teenagers Headquarters, and if you're here, how can you and Wally remember me?"

"Listen Nigel, we were about to be decommissioned, but at the last second we were told that we were the new members of the Teens Next Door."

"The Teens Next Door?"

"Yeah, it's a secret organization that only special KND operatives are allowed to be in after they turn 13. It's the same one Maurice was in when he turned 13."

"Wait... Maurice was never decommissioned?"

"Oh yeah, you didn't know that. Nobody did except for me, a while back he told me that he was an undercover spy for the KND, and he told me that I couldn't tell anyone, not even you guys. Anyway, we were sent here to pick up information on the Teens. We sent tons of information back to the KND, but nothing would work, the Teenagers defenses grew stronger by the hour, and they countered every move the KND made. We shouldn't be here anymore, but we have to stay here until we break through their defenses."

"Well now, I'm here and we can take them down together as a team."

Abby smiles and shakes her head, "Good ole' Nigel"

Abby then goes into her drawer and pulls out a Gumball gun and hands it to Nigel, "Here, you're gonna need this."

Nigel then says, "Right, let's do this."

He's about to do this when Abby stops him and says, "Wait Numbuh 1, I think these belong to you."

She hands him the sunglasses that he gave her before he left for the Galactic KND. Nigel puts them on.

"Now we're ready" Abby says

"Let's go" says Nigel

They kick the door open and start firing at the two guards Wally is fighting.

Tune in next chapter to see what happens to Wally, Abby, and Nigel. Thanks for reading.
