Regulus came awake in the dark and laid there, blinking, noticing the sweat he was covered in. He got up and walked out of his room, making his way to his sibling's room, rushing in.
"Can I sleep with you tonight?" he asked, keeping his voice low, as he sat on the edge of Sirius' bed.
Sirius yawned, nodding, all too familiar with the situation. He wrapped his big blanket around his baby brother after Regulus laid down next to the older sibling in bed.
Regulus sighed at the warmth. "Thank you," he said with a soft tone.
"Anytime, Reggie."
