After reviewing the events of that night, Regulus realized it was probably a good idea to check on his brother. He knew how ruthless his mother could be, and he needed to reassure himself that his older brother was fine. Regulus padded up the stairs, peering around the doorframe, before coming into full view once he verified his parents weren't around. He spotted the older Black, who was packing a trunk of clothes and other various knick-knacks. Regulus sighed softly. "..Where are you goinng?" he asked, his brows furrowing in slight concern for Sirius.

"'Round the Potters'." The other boy responded emotionlessly.

Regulus rolled his eyes, visibly irritated. "How long will you be gone?.." Even though Regulus got no reply or answer, he knew the answer.

Sirius mumbled quietly as he buckled his suitcase tightly. "I'm sorry."
