After the dynamic duo decided to test if Marcellus was a vampire they went to a fridge in what looked like the lab part of the basement. Arthur then grabbed a bag of blood and gave it to Marcellus.
When Marcellus saw the blood bag he unconsciously gulped. He didn't want to admit it but the blood looked really good to him right now. After he took it from Arthur he started hesitating.
"..What if we are wrong?" asked Marcellus, even though he didn't think they were.
"Then this will look really weird" replied Arthur while chuckling.
'Here goes nothing' thought Marcellus as he drank some of the blood from the bag.
As the blood left the bag and was swallowed Marcellus' body started to change again. He didn't grow or look any different but there was now a hidden charm to his overall appearance. His nails grew black and sharpened like steel. The whites of his eyes turned black, while the iries glowed with their original pink and purple mix even more vibrantly. Black veins grew on his cheeks growing from his eyes giving him the same face as Everblood and Alicia. Marcellus didn't notice any of this as he hungrily drank from the blood bag. He felt as if he had been starved and was only now getting a meal for the first time in his life. Or death.
When he drained the blood bag dry he gasped a breath and threw his head back in euphoria. When he tilted his head back you could see in his mouth a pair of elongated canines with an eerie sharp feeling emanating from them.
As Marcellus was experiencing post 'blood' clarity, Arthur was looking at Marcellus with an expression of fear. Then as he was about to listen to his feelings and run away, he remembered his earlier conversation with Marcellus so he braced himself, steeled his will and gulped.
"Marcel, buddy ol' pal" Arthur said in a determined but anxious tone.
Marcellus seeing a human could only think of blood at the moment. He then used his overwhelming speed and attacked Arthur. When he was about to sink his teeth into Arthurs neck he finally heard him.
"MARCEL" screamed Arthur.
As Marcellus snapped out of his blood haze he realized what he did. He tried looking at Arthur but couldn't because of the hunger. He looked away as he managed to calm down enough to speak. As he calmed down more and more his 'vampire face' went away leaving Marcellus with his original one.
"I'm so sorry Arthur I didn't mean to–" Marcellus started to apologize but was interrupted.
"It's fine really, can you control it now?" questioned Arthur with a smile to hide the fear he felt a moment ago.
"I can but not for long, also can you grab a few more blood bags, I think it will be easier to control if i'm not hungry." said Marcellus through gritted teeth as he struggled to not attack his best friend.
Arthur then opened the freezer but at the smell of so much blood Marcellus once again lost control. He sped past Arthur totally ignoring him as he feasted on the blood bags.
6 blood bags later….
"So what about now?" asked Arthur with an expression of anxiety.
"It's still there but I can control it enough to not attack you" said Marcellus with a pensive expression.
"Okay, good," signed Arthur in relief.
"Arthur, I'm going to leave, I don't want to accidentally attack you and I need to go find that girl from the abandoned mansion." said Marcellus with a serious expression.
"I get the first part but why do you need to find the girl who did this to you?" asked Arthur in puzzlement.
"She might have answers to what I am and how to control it" answered Marcellus.
*SIGH* Fine but if she is also a vampire, she might be hungry so bring her this and..if she tries to hurt you again, run" said Arthur in support.
"..Alright, also I'm taking my lamborghini now" said Marcellus who was feeling a little embarrassed at the ill timing of mentioning the bet.
"Starting to think you only hang out with me for my blood and money" joked Arthur as his eyebrow twitched.
"Well it certainly wasn't because of your brains" replied Marcellus as he joked back. He then grabbed a few blood bags from Arthur, the key to the car and then he left.
As it got dark he arrived at the abandoned house….
He went inside and looked around but there was nothing there. Not the knife, or any blood that was spilled during the struggle.
'If she isn't here, I don't think I'll be able to find her again, guess I'm on my own' thought Marcellus in dejection.
*SIGH* 'I'm just going to go home, I have a few blood bags and mom shouldn't be home right now, so I can have some time to myself to think' thought Marcellus as he got into his black lamborghini and grabbed one of the 20 blood bags he had stored in his book bag and started drinking out of one while he drove.
As he was driving he saw a police car and heard the sirens signaling him to pullover. As he started slowing down he hurried to finish his blood bag so he didn't accidentally attack the officer pulling him over. Then when he finally came to a stop he closed his book bag with all of the blood in it and put it on the floor of the passenger seat. After making sure no blood spilled anywhere he sighed in relief and focused, for control.
"Hello sir, can I please see your license and registration?" asked the officer that pulled Marcellus over after walking up to the car.
"Sure officer" replied Marcellus as he showed his papers to the officer. After a glance the officer told him he could have them back.
"Do you know why I pulled you over?" questioned the officer.
"No sir," said Marcellus.
"Then are you aware you were going 30 miles above the speed limit?" asked the officer.
"..No I didn't realize" replied Marcellus in a low tone but enough for the officer to hear him.
Marcellus was telling the truth, he hadn't realized how fast he was going. He was too focused on the blood bag and even without it he wouldn't have realized because of his new perception of speed that came from him breaking his chains.
The police officer seeing that response thought something was wrong. He saw the car Marcellus was driving so he thought, rich kid speeding because he was out of it, he might be on drugs.
"Do you have or have you consumed any illegal substances today?" asked the police officer.
Marcellus panicked for a second but then he realized that the officer was talking about drugs.
"No sir" replied Marcellus with a little bit more force to try to show he was telling the truth. However, he only made the officer more suspicious.
"Please step out of the vehicle, slowly" ordered the officer as he took a step back with his hand on his gun but not pulling it out.
"..Okay, okay" Marcellus then slowly got out of the car as he had his hands up .
The cop then frisked Marcellus, checking for drugs. However, with Marcellus being nervous because of the gun he let himself slip for a second accidentally, but it was too late.
Marcellus' vampire face came out to play again as he lost himself. He spun and grabbed the officer before he could react and sunk his teeth into the officer. Marcellus was holding him so hard that the officer couldn't even scream as he was having his throat torn out by Marcellus' teeth. However, as he was feeding, Marcellus wouldn't be able to hear him anyway.
