"So what does pink mean?" Mishka asked.
"Is there a specific color pink?" Jem asked.
"Nope. He just said pink. And weirder, pink meters ahead."
"Let us take this thing one by one," Yanna said.
"Plane... airplane... flying... jetplane..." Jem enumerated. "... jetplane... jet... Jet!"

Mishka wrote that down. "Okay. Jet! Jet... what?" He stopped writing and looked at the paper. "Arrives? Well it's obvious that that is where he was put in or where he went."
"4:00. We know this letter is from Jet. Now he would give us clues to where he was going to..." Jem remarked.
"That's it! 4:00 is the direction!" Yanna said.
"How can it be?"
"If you will point 12:00 to the north... then 4:00 would be somewhere southeast!"
"Now we think of pink..." Mishka said. The paper which held their clue now looked like this.

They walked back and forth "4:00" trying to figure out something. Also, they watched for suspicious houses along the way.

After a long night's sleep at the room Jasper purchased for them, they continued searching for the meaning of Pink.
"Mishka, think of everything Jet was fond of. It might give a clue," Jem suggested.
"Alright. Well... for one, he liked learning different languages," Mishka said.
"Well that won't help unless "pink" is German or something," Yanna gloomily added.
"Unless... pink IS German!" Mishka said.
They laughed.
"And," Mishka added. "He liked doing stuff with his computer. Building websites and such."
"Nice, we could let him do the Pfkada official website," Yanna said.
"He taught me a lot too... He also does this math thingy. I'm not sure if it really is math. Converting hexadecimal numbers to decimal numbers to binary numbers to somethingy numbers. A hobby I think. Or maybe helping him in creating his websites..."
Jem suddenly remarked, "Websites! That's it! He converts hexadecimal numbers to decimal numbers, loves making websites and liked different languages! Thanks Mish!" Jem said. She told Mishka to open his computer.

"Mishka, come on. Come on." Joshua muttered to himself. Suddenly, the name "Mishka" came up on yahoo messenger. Josh started the conversation.

Joshua: Hi Mish. How are you guys and Jet?

Mishka: We're doing well. We figured out the note Jet sent us.

Joshua: Oh. Us here have found somebody in help. You know, just like Carlos. Speaking of Carlos, somebody should go after him.

Mishka: Oh. By the way, Jem is asking what the hexadecimal code for pink is.

Joshua: Here: FF00FF

Mishka: Can you convert it to decimal?

Joshua: Slowly, I'm becoming a BOB (Beast of Burden). What is this supposed to be for?

Mishka: The number of meters southeast to Jet's location.

Joshua: Then I suggest you take a plane, coz it's a really high number of meters. Might I suggest something?

Joshua: FF = 255

Joshua: 00 = 0

Joshua: FF = 255

Joshua: Add them all together, you get 510.

Mishka: Thanks Josh.Regards to everyone else. Hi from Jem and Yanna to everyone there. And Ren too.

"They're doing all right." Joshua told the others as the car slowed down to a halt.
When Jasper, Almira, Nicah and Joshua got down, it wasn't what they expected it to be. Carlos's place was a bombed forgotten old place. This time they dropped in at what seemed to be a party.
