A/N: To Trinity Fenton-Phantom: Typically I WOULD make that happen, but one of the rules was that Danny couldn't be revealed. Now, if you readers WANT me to do what I did for 'He's Back' and do a rewrite with a different twist, I will. Just let me know via P.M. or review (and no flames)

Chapter 4: The Lab

A week later,

Team Phantom walked into the Ghost 101 classroom bright and early and saw a VERY eager Valerie sitting in the front row

"You seem eager" Sam said accusingly

"This is my favorite class" Valerie told her. "I never knew there was so much to ghosts."

"I'm sure if you let Danny Phantom get a word in edgewise, he could tell you all you're learning from the Fentons…OW!" Tucker said

Sam had stomped on his foot while Danny elbowed him and Jazz whacked him upside the head.

"You four know Phantom?" she asked

"Don't tell Mom and Dad." Danny whispered. "but he saved our lives a few times so…in return we promised to keep our involvement with him a secret"

"Why would he save your lives?"

"No clue." Jazz lied

The bell rang and the rest of the class poured in followed by Jack and Maddie (Jack had found the Teacher's Lounge and had been enjoying himself)

"Okay Class" Maddie said since this was her turn to teach. "We have a busy week ahead of us. Before class ends today, do NOT forget to pick up these permission forms. We'll also be doing our first lab this week and your first group project will be assigned. Any questions?"

"About ghosts!" Jack added

Valerie raised her hand

"Yes Valerie?" Maddie called

"Why would a ghost save a group of people?" Valerie asked taking care not to name names.

"This is about Phantom?" Maddie asked

Valerie nodded

"Well, it could be for a number of reasons"

"The first is that he's being very egotistical and wants the fame and glory" Jack said

"OR," Maddie put in. "if his death was recent, then there's a very small chance he remembers a bit of his past life. If that's the case, the people he saved are probably some old friends or family of his or they remind him of himself and his friends and family. Now, if you kids will pair up, we'll go into the lab. Since you were acquainted with the lab last week, we'll just get started

Danny fiddled with the ring a bit to make sure it was very secure before going into room 223B and grabbed his new white and black hazmat suit

"At least it's not inverse" Sam whispered

He agreed. If it was, then all that was needed for his eyes and hair to change and he would be his ghost form.

Jazz slipped on a pink and black hazmat suit that had looked like her first one while Sam put on a purple and black one. Everyone else got either orange or blue

"How come yours are unique?" Tucker asked Danny, Sam, and Jazz

"We asked" they chorused

"Okay Kids. Pair up"

Tucker and Jazz winked at each other and pushed Danny and Sam towards a station so that they were stuck as lab partners. And just to keep things between Team Phantom, Jazz and Tucker paired up. Poor Valerie got stuck with Nathan

"I saw that coming" Jack whispered in a singsong voice to his wife when he saw who his son had paired up with

"Jack. Leave Danny alone" Maddie whispered back as she pulled out a guide. "Now, each station has some samples. I want to know if you kids can see which ones are ectoplasm by use of the dye we showed you last week."

Sam pulled out the bottle with the eyedropper in it.

"I want to try something first." Danny whispered as he looked at the first slide which set off a bit of his ghost sense.

He looked into the eyepiece and saw no signs of ectoplasm. But he knew it was there because of his powers. He then willed his eye to turn neon green (one of the advantages of having parents as teachers and a sister in on the secret was more time for training). Sure enough, it started glowing a little.

"It's a little bit of ectoplasm" he told Sam.

She put on the dye and looked.

"Probably…2%" she figured as Danny wrote it down

She then grabbed the second sample and held it in front of Danny's face. Nothing

"Sample 2, no ectoplasm" Danny wrote as Sam used the dye to double check

"Right" she confirmed

At the station next to them,

"Ah man!" Tucker said realizing what Sam and Danny were doing "Why didn't I think of that?"

"We'll just do it the way normal people do" Jazz told him

"HEY!" Jack yelled at some senior boys who were starring at Jazz and not the samples. "Eyes on the samples! NOT my daughter!"

"DAD!" Jazz exclaimed

"I have an idea." Danny said as he pulled a spare slide and a scalpel.

He took off his glove and pricked his finger and allowed some of the blood to drop on while Sam was keeping watch knowing what he was doing. Using his ghost powers, he healed the tiny wound and replaced the glove.

"Okay" he told Sam

She put the dye on the blood and they slipped the slide under the microscope.

"The blood cells are only glowing a bit…like the 2% sample" Sam said moving and allowing Danny to view his own blood

He looked and saw the red blood cells with the glowing cores

"It must be on a molecular level" he mused

"Must be" Sam agreed

After the lab,

"Okay class. We only have 5 minutes left of today's lesson" Maddie said as she passed out the permission slips to all but Danny and Jazz. "We are scheduling a field trip…"

"YEAH!" the class cheered

"To the Ghost Zone," Jack continued. "There we will see certain ghosts and you kids can prepare for the group project where each group will be assigned a ghost and do a report on it"

"We'll be assigning the ghosts because I don't want every report to be about Phantom" Maddie told the class

Danny felt a note enter his hand from Tucker. Danny looked down and read the note

Be Funny if WE got Phantom

Danny nodded in agreement
