Meanwhile, Raph, Donnie, Mikey, Casey and April were in the lab, trying to come up with a plan for their encounter with Shredder.
Suddenly, they heard a sound.
"What was that?" asked Casey.
"Leo, I mean Tommy and Master Splinter are out there," Mikey pointed.
"Let's hope Karai didn't trick us, and Shredder's here," said Raph.
"As much as I hate to say this, but Casey, you stay here with April, while we check to see where the commotion's coming from," said Donnie, not wanting to leave his "crush" April alone with his rival Casey.
Once Raph, Donnie and Mikey raced out of the lab, they found a nervous Splinter sitting on the couch.
"Master Splinter, are you OK?" Raph asked his teacher/father.
"Don't worry about me.
I'm fine, but Leonardo has vanished," Splinter replied.
"What happened?
Where's Leo?" Donnie asked.
"I wish I can answer.
I just turned my head for a few moments in the kitchen to make us tea, I heard this loud noise, and that's when I noticed he was gone."
"We've gotta fine him.
"Leo, er Tommy!
Here Boy!" Mikey called out.
"Mikey, Leo's a turtle not a dog."
Raph dashed back into the center of the lair and said, "Well, I've got some good news and some bad news.
The good news, I think I know what happened to Leo.
The bad news is, he left the lair, and he took the party van."
"Leo, driving the van in his condition?!" Donnie basically screamed.
"Not to mention he's at risk of getting spotted!"
Upon hearing the commotion, April and Casey rushed out of the lab.
"Did you guys say Leo is missing?" asked Casey.
"He is, and he drove off in the party van," Raph replied.
"This is terrible!
He could get seriously injuried, or even spotted," added April.
"Exactly.
We've gotta go up to the surface and look for Leo."
"We better split up, I think we'll have better chances in finding him," Donnie suggested.
"Good idea.
Casey, you come with me, Mikey you stick with Donnie, and April, you stay here with Splinter, in case Leo comes back," said Raph.
"Guys, I'm almost a full kunoich.
I'm coming along," said April.
"What about Master Splinter?" asked Mikey.
"I'll be fine on my own and wait for Leonardo's return," said Splinter.
"Alright then, April, you're with Donnie and Mikey," said Raph.
Despite the situation, the purpule bandanna wearing turtle couldn't help but smile, as his "crush" was teaming with him.
As the five of them headed out, Master Splinter called, "Be carful my sons, Casey, and April."
"Don't worry Master Splinter, we've got this," Raph assured the team's teacher/father.
"We'll find Leo and bring him home safe," April added.
Once they made their way out of the sewears, the three turtles and their human friends split up into two groups with Raph and Casey heading west, while Donnie, Mikey and April headed east.
But while they went into two different ways, they had the same thing on their minds, which was to find Leo and hope he was safe.
As his brothers and friends were on the search for him, Leo was in another part of town, Leo was driving the party van (very poorly) in another part of town.
"Excuse me!
Sorry!
Pardon!" the blue bandanna wearing turtle called out to the people in the streets, running away for his terrible driving.
During the search, Raph and Donnie checked in with one another every few minnutes or so to give an update on finding their missing brother.
However, both groups were not having much luck.
A short time later, Donnie, Mikey and April were searching for Leo in another part of town, from the rooftop of a nearby building, when the purple bandanna wearing turtle's T-phone went off.
"Raph?
Any luck finding Leo?" Donnie asked, after answering the device.
"Not exactly, but you MIkey and April need to meet us at 10th street asap!" Raph answered.
"We're on our way!"
After Donnie placed his phone away, April said, "I heard Raph found something."
"Did he find Leo?" asked a hopefully Mikey.
"Not exactly, but he wants us to meet him and Casey at 10th St right away," Donnie replied.
The three rushed to meet up with the others on the other side of town.
Donnie, Mikey, and April jumped from rooftop to rooftop to reach Raph and Casey.
Once they met up, April asked, "Raph, Casey, what did you find?"
"Did you find Leo?" asked Mikey, who was basically, jumping up and down.
"No, but we did find something else," Raph replied.
The three turtles, April and Casey climbed down the fire escape, connected to the building and went to see what has been found.
When they reached the area, April let out a sight gasp.
As it turned out, what Raph and Casey found was the party van, lying on it's side.
"Get the van up!" Raph shouted.
He, Donnie, Mikey and Casey pushed the van up, using all their strength.
Once the van was placed up right, the three turtles, Casey and April went inside to look for the missing team leader and eldest of the bunch.
"Leo!
Leo!
Are you in here?!" everyone called out.
However, there was no answer.
But, there was proof Leo was here by what Raph found on the floor.
It was Leo's kanta ninja sword.
"Leo never goes anywhere without his sword," Casey pointed out.
"Well, since his name is Tommy now, anything could be possible," Mikey concluded, which earned glares from Raph, Donnie April and Casey.
Getting back on the subject, April asked, "What do you think could have happened to Leo.
"Maybe he woundered off after the van tipped over," April suggested.
"I don't know guys, judging by the look of the van, something tells me Leo didn't wondered off," said Donnie.
The purple bandanna wearing turtle was right.
Many times that the party van had turned over, almost all of the equipment stayed in place.
However, the inside of the van looked as though a hurricane had it.
"D, you don't think Leo was taken?" asked April.
"As much as I hate to say this April, but I think Donnie maybe right.
And I have a feeling who is the most likely canidate," answered Raph.
"OH NO!
Leo's been kiddnapped by radiactive chipmunks!" Mikey screamed out, before earning a slap on the back of the head, courtesy of the red bandanna wearing turtle.
"Uh Mikey, dude, I think Raph had another name in mind," said Casey.
"Shredder," Donnie and April said at the same time.
"Exactly, and I also wounldn't be surprised that Karai maybe up to it as well," said Raph.
"Really?
You think so?" Casey asked.
"Yeah, I mean think about it.
If it wasn't for her, Leo wouldn't be in this mess.
And for all we know, she could be trying to trick us."
"Raph, I know you're upset about the situation and you're very concerned about Leo, which I'm glad you are.
But right now, this is no time to put the blame on anyone.
What's important now is that we find Leo and that he's safe," April point out.
"April's right Raph.
Let's get to Arthur Avenue, hopefully find Leo and bring him back to the lair," Donnie added.
And that was exactly what the five member team did.
