Karkat sighed as he looked at the mirror, ignoring the eyebags that were beginning to grow under his eyes. He gripped the notebook by his side tightly as he triple checked that the door was locked. He really didn't want to be disturbed.

With a deep sigh, he opened up the notebook to the page about himself. He couldn't help but read over the notes, reviewing them carefully.

Subject has lower than average body temperature, currently about 72.3 degrees. Has lower than average heartbeat, usually at half the amount of a normal human being. May be related, but hard to tell. Billows smoke whenever other ghostly entities are nearby…

He tore his eyes away from it, rubbing them to get the words out. He didn't have time to reread his notes, he needed to check himself over now. He'd been putting it off since the accident and he needed to know if anything else changed, especially in his human form. Karkat sure as hell didn't want to know if something weird would happen if he went to a doctor's appointment.

Another sigh escaped him. He had to look himself over before he lost his nerve again.

The first thing he checked was his teeth. Flicking his tongue over them, he noticed that few almost felt sharper than they normally were. God, were fangs going to be in his future? He should look out before somebody tries to audition him for any Twilight reboots. That would a hell of a career move.

Subject has slightly elongated canines. Unknown if they will grow in the near future, especially to exaggerated levels. Will more teeth sharpen or grow in the future? Or will the growth stop at canines?

He clicked his mouth shut. His hand grabbed onto the light nearby, eventually plunging the room into darkness.

He was disturbed to note that even if they weren't in ghost mode, they still glowed. Not in an obvious way, of course, but if you bothered to look for them, it was kinda obvious. Guess he wouldn't be going to any unsolicited slumber parties then. At least he can see in the dark, though.

Subjects eyes glow whenever light in the area is not optimal. Slightly noticeable in the whites of his eyes, but most apparent in the iris. Could be due to strange color of the eye making it appear to glow that makes it more obvious. Grants night vision of a sort to the subject as well.

He certainly upgraded in the senses department, that was for sure. He wondered if his hearing was increased too. He really hoped not. Karkat was sure of many things in his life, but he didn't want to be able to hear his neighbors have sex or something.

…Then again, if he focused hard enough, he could actually hear his dad working in the lab. Nothing specific, but he could tell he was there. He could even smell certain things when he took the time to and he could've swore some colors worked differently.

The senses of the subject change depending on specific focus. Can smell quite a bit better, possibly has colorblindness corrected, and increased hearing. Not exactly amazing just yet. Could get stronger through practice? Can senses get stronger that way?

This wasn't even the more interesting tests he got planned. The fact that he was in puberty, late stage or not, meant that maybe he could grow bigger and get even stronger depending on how the hormones in his body decided to change him.

And the list of questions of how this accident effected him only seem to get longer and longer.

How strong is the subject?

How fast is the subject?

What happens if the subject injects/eats ectoplasm? Filtered? Unfiltered?

How did the accident change him?

Does exercise in one form increase the strength of another?

Does change in psychological profile/shift in personality change ghost form?

Are there further changes to the subject's human form that aren't obvious? On the inside?

Could the accident happen twice?

Can the subject be legally considered a human?

How will the powers develop? From his psychology? Or from subject's natural DNA?

Am I a mutant now?

Can the changes to the subject's DNA be sustainable?

Is there ectoplasm in my blood or blood in my ectoplasm?

Karkat slammed the notebook shut, breathing deep and heavy. More questions kept coming and he didn't know the answer to them anymore and he was honestly unsure of how to get rid of them. His throat was closing up and he could feel his eyes watering.

He clamped down on the rise of emotions running through him, taking a deep breath.

"Think like a scientist, Vantas. Think like a scientist." Karkat sucked in a wet breath, letting it out shakily. "Can't get any answers if you freak out. You won't get shit done if you do."

Looking into the mirror, he didn't get any answers. All he saw were glowing eyes.
