After welcoming to the castle the maids John and Roselyn returned to Kratez and John soon called the doctor to make him see Roselyn.

In about one hour the doctor arrived, he seemed very old and his green hair fell like a cascade over his shoulders. He was pretty robust but if it wasn't for the color of his hair and eyebrow and the way his eyes sparkled of an intense blue Roselyn would never believe he was a supernatural creature.

"Welcome. Thank you for coming as soon as you could." John said to the doctor who nodded walking closer to Roselyn who was laying on the sofa.

"She is a banshee," John said and the doctor nodded like if already knew.

"Roselyn, can you explain to me how do you feel during your fainting?" The sir said grabbing her arm and wrapping a pressure gauge over her arm.

After a long detailed explanation, the doctor cupped his chin in a thoughtful expression as she kept monitoring Roselyn's heartbeat and pressure.

He then removed the pressure gauge to head toward his suitcase and open it. A dozen of syringes and mini bottles were inside but the doctor grabbed only one syringe and began to drop liquid inside it.

He grabbed the filled syringe and pointed it to the ceiling as he reached Roselyn.

"I will get you a shot now." The doctor said but as soon as he headed the syringe's needle over Rose's arm John speeded toward him to crash him against the wall.

"I didn't call you here to do experiments on her." John groaned and Roselyn opened her eyes widen in shook.

The doctor tried to move but John crashed him again against the wall having him scream in pain.

"I need to extract a drop of her blood to analyze…" before the doctor finished John groaned even more aloud as he revealed his long sharp fangs and the doctor flinched away squeezing his eyes in fear.

"Try to hurt her and I will kill you." John threatened, his voice sounded so threatening that even Roselyn shivered.

"I-I-I won't harm her." The doctor stuttered shaking in fear. He knew what John was capable to do and he didn't want to stand against him.

John was probably the strongest creature in Kratez and was knew for the infinite amount of lives he took. The doctor knew very well he wouldn't think twice before adding another victim to the countless number of murders.

His mouth dried, he was agitated and cold sweating. If he even unintentionally harm Roselyn it was over for him.

"I promise." The doctor insisted and John finally let him go.

He walked back toward Roselyn and leaned the needle toward Roselyn's arm. The lady offered him a supportive smile when she perceived the doctor's agitation and fear.

With an unsteady touch, he shoved a giant needle in her arm and extracted some drops of Roselyn's blood.

Roselyn felt the needle pinch inside her skin but she tried her best not to make any grimace of pain as she knew John would kill the doctor in case she did.

When he finished the blood sampling he inserted a transparent substance inside of the syringe and he tapped with his fingers to mix the liquids.

The orange liquid mixed with Roselyn's blood as the doctor kept tapping over the syringe, the blood dissociated into particles until it fully mixed inside the substance which took an odd yellow color.

The doctor dropped his jaw, he didn't expect that to happen he held his breath as he kept tapping against the syringe and whispering "it can't be.".

John frowned his forehead knitting his eyebrows down, "what happened?" he asked quite concerned. He was already very tense and irritated because smelling Roselyn's blood made him remember and crave her blood but he had to focus to control himself.

The substance remained of yellow color and the doctor swallowed down gazing at Roselyn preoccupied.

"What happened??" John raised his voice irritated, clenching his fists to control now the impatience for leaving him hanging.

The doctor swallowed again before taking a long breath. "Based on the color the substance took it should show the chances of a supernatural creature to get pregnant." The doctor began to explain and Roselyn held her breath waiting for him to continue.

"If the substance mixed with Roselyn's blood turned red it would have meant she was pregnant. If it turned blue it would have meant she didn't have any chance of getting pregnant." The doctor stated narrowing his eyes and darting his gaze between the couple.

"But the substance turned orange," John addressed waiting for an answer.

The doctor nodded before swallowing down once again, "if the substance assumed an orange color it would mean… she had very minimal chance of getting pregnant. Very minimal percentage but still a possibility."

Roselyn's eyes sparkled with joy and filled with tears of happiness, she smiled hugely and seeing her that happy made John smile as well.

But then why the doctor seemed so worried?

John ran toward Roselyn to hug her tightly, he knew how much it meant for her to be pregnant.

The doctor took advantage of John's distraction to grab another syringe filled with a black substance he hid his hand behind his back and walked closer to John.

"Congratulations!" the doctor exclaimed and John turned around smiling joyfully at the doctor. John opened his hands to hug him overwhelmed by joy but right when John spread his arm the doctor threaded the needle in his arm and John remained frozen before falling down the floor unconscious.

"I am sorry…" the doctor said, slipping the syringe over John and walking closer to Roselyn.

Roselyn looked at him frightened and puzzled.

"I can't let you have kids." The doctor continued leaning the syringe over Roselyn's arm.

Roselyn worried tried to get up from the sofa and run away from him but as predictable the doctor speeded toward her and before she could turn around he already injected the black liquid in her arm too.
