A/N: Short and sweet? We'll see.

Ah, Bio 2, the one class that Danny has with both Sam and Tucker, and the one class that Danny was naturally decent at this semester.

Well, naturally probably isn't the correct word. He wasn't amazing at it before the accident, he was more of a chem guy, but after he started ghost fighting these sorts of things just kind of… clicked.

Maybe it came with the semi-regular perusing of videos that are medical in nature. Danny clicks on a video about binding a wound that interests him and could possibly be useful after ghost fights, and the recommended videos distract him for an hour or two. Well, that is… until he gets to the weird part of YouTube where they have full-blown surgeries and stuff. Can they even show that on there?

Nevertheless, he's excelling. Rarely having to study, having little homework, and more in-class labs allowed Danny to maintain a decent grade even when the ghost-getting was tough. Now he can maintain a solid A without much work.

But… he does tend to slack off sometimes.

"Hey Danny, you better get off your phone, he's going to describe the instructions now." Sam nudges him in the shoulder to grab his attention, but ultimately fails.

"Uh huh" he mumbles, barely noticing the disturbance. Sam rolls her eyes, reaching over him to poke Tucker. He looks at Sam, who gestures to Danny with her eyes.

Tucker looks over at the distracted ghost boy and simply steals his phone from him, securing it in one of the pockets of his cargo pants.

"I- Hey- Tuck!" Danny whispers. "We're just doing blood testing, it isn't even that complicated. The lab sheet has all the instructions on it!" Danny reaches for the pocket of Tucker's shorts, trying to get his phone back.

Tucker turns away. "You should still pay attention, how are we going to-" he glances at Danny's mouth. "Uh, dude? You're drooling. A lot."

Danny momentarily forgets the struggle with his phone and wipes his mouth. He is indeed drooling.

Sam looks at Danny as well to see what's going on. "Oh boy, it's green too. And…" she squints at his face. "Glowing?"

"Yeaaah, this hasn't happened before." Danny looks at the substance smeared on his hand. It's quite a lot thinner and more translucent than ectoplasm, but it's still ectoplasmicly based. (Is that a word?) It does have a faint glow to it, too.

"Foley! Fenton! Manson!"

All of them snap to attention at the teacher's bellowing voice. Danny quickly shoves his hand under the lab table.

"I honestly couldn't care less if you don't want to pay attention, but please do not disrupt my class with your talking."

Sam speaks up. "Sorry Mr. Marx, won't happen again."

He nods and goes back to writing on the whiteboard. Meanwhile, Tucker takes a quick photo of the smear on Danny's hand. (While he intangibly steals his phone back from Tucker)

Sam gets Danny's attention again and gestures for him to open his mouth. He takes another glance at Mr. Marx, who's still writing instructions furiously, and opens.

Sam simply looks for some time before grabbing her notebook and scribbling something down. She pushes it to Danny and Tucker.

Looks like it's stopped, but your canines look sharper too, and your tongue is less pink and more grey, and pointed a little... I think?

Danny reads the note and holds his head in his hands, making little, frustrated noises all the while. After a bit, he writes back.

great, another thing I have to hide. When does this stuff even happen?!

He pushes the note back to Sam, rubbing his face with his hands. Tucker reaches over and slides the notebook back to himself. He scrawls something down and then passes it back in front of Danny.

don't worry dude, we got your back. :)

Sam reaches over and writes something as well.

Of course! Plus, it seems like it's only noticeable if you're really looking for it. We'll talk to Jazz tonight, maybe she has some insight.

Danny sighs and smiles sadly at both of them. He grabs his pencil, hesitates, and then writes.

Thanks, guys.

"Alright students, I want this done by the end of the period. That leaves you half an hour to record each of your results and turn it in, understand?"

Some of the class responds, and then faint murmurs can be heard as everyone gets to work.

"So, as I was saying before." Tucker turns to Danny. "How is your blood testing going to work?"

A/N: Uh oh, what's happening to Danny?

Are you guys interested in the story so far? Anything you think I should address/anything confusing! REVIEW!
I promise I take criticism real well, don't be afraid to say anything. :3
