Mattheo wanted to keep you away from the dark side. He didn't want you getting involved in his father's business. He didn't want to be involved in his fathers business. He didn't exactly have a choice, though. But you did.
You could choose to stay away from the war, the constant pain the pressure of doing something so wrong that it would give you nightmares. But even then… you chose to join them.
Mattheo was sitting quietly next to his father at Malfoy Manor. He had been blocking out most of what was being discussed.
"We have a new member." His father announced. Mattheo's gaze stayed trained on the table. He didn't care for all this. He heard the door open and a set of soft footsteps. His eyes snapped up. He could recognise your footsteps anywhere.
You didn't look at him or any of his friends. You walked up to Voldemort, bowing in front of him.
"My lord," You said, your voice raspy. Voldemort pulled out his wand, his bony fingers barely wrapping around the hilt.
"Give me your arm, girl." He hissed. You held out your left arm, your sleeve pushed back to your elbow. Mattheo watched as his father pressed the tip of his wand to your forearm.
He wanted to scream, to tell his father to stop, to tell you to get out of here. But he didn't. He watched like a fool as his father etched the mark into your skin. He watched your eyes glaze over from the pain.
You blinked away the tears, bowing again and made your way to an empty seat. Mattheo's eyes followed you. You finally looked at him once you were seated next to Avery II. You didn't look like you regretted your decision; it made Mattheo's heart clench.
Why? Why had you done this? He blinked back his rage and his sorrow, knowing his father would sense it if Mattheo wasn't careful. He shot you a look, "We'll talk about this." it said.
