AU. OC. Post war. Trigger Warning: Rape. Pregnancy.

Rein is Severus's apprentice. A mysterious pregnancy and their lives change forever.

Rein adjusted her clothes before she opened his office door. Severus was at his desk, his grade book open and a quill in hand. His hand paused, his eyes glancing up before he finished his marking. He put his quill down carefully before he sat up straight.

"Miss Stephen, you are to knock before entering my office."

"I have something important to discuss with you, professor."

His face showed no emotions and she smoothed her hands along her skirt. For a brief moment, she thought his eyes had followed his hands but she knew she had to be imaging that.

"The importance, or lack thereof, does not excuse rudeness."

"Please, I really need to talk."

Severus growled, motioning to a chair. Rein sat before she resumed standing, pacing in front of his desk.

"Speak, woman. I don't have all night."

"I think I might be pregnant." Silence followed her statement and she turned to face Severus. He raised a brow, putting his fingers together.

"Having sex tends to lead to that possibility. Have you informed the father?"

"That's the thing – I've never had sex before. Ever." The look he was giving her was unbelieving. "Seriously, I haven't so much as kissed a man this year – how could I be pregnant?"

"Do you expect me to believe this? Fess up to the father – or has there been so many that you don't know who the father is?"

"Severus, please! I'm not making this up." She sat heavily in the chair, putting her hands on his desk to steady herself. "I went to bed, by myself, but when I woke up this morning, something was different."

"Something was different?"

"Yes. I don't know how but I know I'm pregnant." She put her hand on her belly. "My magic is different."

Severus stood, coming around his desk. "Then you should see Poppy about confirming your suspicions. You might be wrong."

"You don't believe me?"

"How can I?" He hissed. "One Virgin Mary is enough, thank you."

She stood, her face set. "Someone impregnated me without my consent – why can't you believe that?"

"Because this could all be in your head! Confirm with Poppy and then talk to me."
